I apologise if this will be a long post and i hope someone can give me some sound advice about this.

Background info:
Been in an exclusive long distance relationship with this girl for 8months. She's a 7.5 at best which i consider gorgeous as I've met only handful of 9's and never came across a 10 as of yet. She fell head over heels for me when we started going exclusive (said she loved me first night), which freaked me out a bit as this girl didn't even know me. I should have taken it as a red flag but it was at a time i was absolutely pulling insanely and f-closing a high percentage of those pulls so i blew it off as my game getting very good, and girls are insane afterall push the right buttons they'll do anything. she wanted me to meet her parents within the first month and was already discussing babies and all. something never seemed right when i was with her, i found it very difficult to get and keep it up, she would get very upset over nothing, she constantly bad talked her exes, she would constantly indirectly put down my cocky and playful personality and over the months it has reduced to submisive and cautious.
in the first four months i found messages she would exchange with other men and her exes, it seemed very strange as EVERY single one of them was saying they miss her and want her back. was she dating them all? i mean they were alot! she would tell some of them she loved them and missed them too. i confronterd her about it and she said they were just chatting, it meant nothing. that's when i started losing my self respect...
She fell pregnant shortly afterwards and claimed it was mine, i fell ever more deeply. we constantly had fights and in the last two months i found out she was lying about where she was staying when at school (same hometown but we study in different places), where she was attending tertiary, her age, basically alot of things. i dumped her, she cried and followed me like no one has ever, it was even shocking (Walking in the streets barefoot and completely naked with just a robe on to come knock on my window at 4 in the morning etc.) i took it that she really loved me.
Last week she came out early at uni which was strange and she took her phone with her which she never did, confronted her about it, she lied over and over till i dumped her then she told me they raped her blah blah.
The dude she said raped her calls me tells me everything, that they were dating, he fucks her regularly no protection, its his baby and all that. she denies it all to the point where I dont know what to believe.
How do i let go of this girl? she got some hold over me I cant explain. I've even been reduced to binge drinking and thoughts of suicide, I'm emotionally a wreck. it's not love, there's a deep imbedded issue and reason why i can't just let her go and i need to know what i can do to get over it.
Any advice guys?

I've read tons of pity stories on here. But yours just takes the cake. It's beyond pity -- it's fucked up. So is she. For texting her exes and saying she misses them and loves them? Sounds like she doesn't have much of a head on her shoulders, if any. Think about your life now, and imagine how it would be 5 years down the road if you stuck around... Pretty shitty on all accounts I'd think. I'd be smashing the eject button in a panic.

But you're having trouble letting go because obviously you love her. But this is toxic love. Fucked up love. You don't want to hang onto that. And no matter what you do, it will take a very long while for you to cleanse your system of this toxicity. But the first step is recognizing you need to move on. The second is to block all communications with her, start hitting up other girls, and always stay occupied. And on top of all, good luck.

If you're having suicidal thoughts, you need to seek professional help. Though the people on this board are well-meaning, no one here is credentialed enough to help you after something like that. I wish you the best, man.

Thanks for the input Fly Swatter it's appreciated. In my head I guess I already knew what had to be done, I just needed the perspective of someone looking at the picture from outside. I recognize the need to move on, I'm starting the no contact part as we speak. I've been getting alot of approaches and IOI's from girls on campus as I am goodlooking yet I never followed up in sick loyalty to this girl. I'll be mixing with girls to get my mind of her. I'll still drink, it just seems to lighten the load, but i know it's not a healthy way to deal with this, but I'm thinking of it as training wheels for now. I"m looking forward to a bright future without her

Is it your baby? You need a paternity test

I'll definately be looking to do a paternity test once the baby is born. And ofcourse ready to accept full responsibilty for the child if it is mine

If you're gonna drink, limit yourself to a few beers with good friends. Don't get blind drunk in a situation like this.

Cut ties and run, block all communication. She chick sounds insane, she will drag you down the rest of your life if this continues. You may even need a restraining order put on her. Slow the drinking down and seek professional help for the suicidal thoughts.

Ask yourself, is she really worth it? If not, let it go man, it is not the end of the world for you. Many girls out there who is willing to commit their self for you. Go out, meet someone, and have fun. Forget her, and just focus for yourself.

It's you who didn't let her go. Are you one of those trying to save a damsel in distress kind of guy? Or are you married? Married men usually go for these type -- no strings but great fuck.

There are plenty of girls like what you described. They make great playmates or F.B or F.W.B. THEY ARE NOT relationship material. You should be smart enough to wear a condom when you had sex with her? Catching STI isn't fun especially she's the active kind. If you do wear a condom, then it's likely that's not your baby. Do not become responsible for her faults. She is looking for a chump who will pay for her baby costs and some, while she'll go out fucking some more dudes unprotected of course. These girls who go bare back on guys are just nuts beyond believe. If you don't want to let her go, I hope it's because she's got your cock all the time and make you cum so good. But if you want to save her, don't.

Must admit I kinda did wanna save her, she seemed so innocent and vulnerable at first. But she turned out so vicious and crazy. I thought I could help her get through all the lies and bad behaviour and make her a better person. I realise now I was fighting a losing battle

UPDATE

Tried to go no contact since yesterday, was doing well and all ignoring her calls, blocking her on my social networks etc. Thoughts of her taking revenge and sleeping with other men and messed up shit like that constantly haunted me but i tried sweeping it aside. Went out partying last night to meet some new girl, I was awful! amazing what 8months of monogamy did to me. Managed only one n-close, she was a 6 and showing alot of interest, even asking my number and offering to call me. I tried to take that litltle victory and use it to propel me to my target of hb8 and above.
The crazy ex called again today and I regressed and picked up. She said things that got to me emotionally and almost pulled me back, but I decided to hang up and switch off my phone. Felt awful afterwards, but it's for the best right?

Dude stop fucking yourself over DO NOT CONTACT HER UNDER ANY CIRCUMSTANCES, you need to delete her phone number and cut off all social media contact with her, if she keeps calling you change your number or else you'll regress like you did today. In the mean time keep sarging and going at other girls once you get another lay this chick will be out of your mind.

Normal. You won't be perfect in this recovery. But you're probably doing better than I ever did when I went through a similar phase. Also, as someone else pointed out, if you're having suicidal thoughts AND in need of alcohol to lighten your problems, you might consider professional help. I've been there. The only difference was that I was driving under the influence. Not cool.

Update

Got a call from her mother this morning, she attempted suicide and hanged herself. Fortunately they got to her in time. She's in hospital now being stabilized and recovering. What the hell is going on? This isn't normal to me. Do I support her, be there for her or do I distance myself and focus on my life and in doing so cause another attempt (God forbid a succesful one)? I'm only 21, this should not be happening to me
