Hey guys, this could get a bit lengthy so for you who don't like to read a lot of text here is a point form summary:

-Met her in jr high school dated from grade 9 to 3rd year of university. (5-6ish years)

-she is 20 and EXTREMELY beautiful HB9.5 and i am 22

-while we were dating, it was the best 5 years of my life she is incredible and I honestly thought she was my soulmate. We were literally inseparable and had sex every time we hung out

-we had and still have almost everything in common its weird

-my parents loved her from the start, her parents hated me from the start (first bf? I did nothing wrong i swear. I never have figured out why they hate me)

-anywho, cut through the bullshit, she randomly dumps me one day when Im at her house stating "she needs time to find herself" or some bullshit like that. i go HARD AFC due to not knowing about this site. I am so embarrassed when I look back. obv it doesnt work and i go no contact for the summer. we kinda get back together for a week during the summer and I fuck her a couple more times but it fizzles out quickly

-at the end of our relationship she was always texting this guy who lived 5 hours away and swore they were only friends. i got jealous and angry when she texted him (mistake i know). she hangs out with him the whole summer after we broke up (rebound?)

-fastforward 6 months after the inital breakup and i fuck her again at a school event. she invites me over a week later to tell me something "that i will hate her for". I go and she tells me she cheated on me with said friend when he drove up to see his sister about 1 week before we broke up.

-i go no contact for a week cause i am pretty hurt obviously. but eventually we start hanging out again as friends and every time we have had sex. And i mean this sex is un-fucking-real. Better than porn. She does literally anything i want now. before she would shut me down all the time. She initates all the time and buys lingerie (sp?) and new lube and stuff to spice it up. its incredible and better than ever before

-now the important part she talks about wanting to maybe try and get back together in time and work on ourselves and each other and shit. My family (immediate and relatives) absolutely hate her now cause she destroyed me. effectively she cheated on me and dumped me for another guy and it didnt work out so now she wants to try us again. the only thing that makes me want to keep going is the sex. we are not exclusive at all right now. just friends with massive benefits. but i know it wont work. so my ultimate question is:

How do I tell her that I don't want to get back together ever? She ruined me for 5 months. It was really hard for me and the whole time she was fucking some random loser who she later told me has a small dick and never made her cum or fucked her like i do. How do I politely tell her to go fuck herself pretty much?

You have so much to learn about the art of administering revenge.

Enjoy her while you can, if she is truly sho hot as you believe. In the meanwhile, plot your revenge for what she did to you, hook up with other girls, whatever.

Perhaps she just did this guy to find out what it was to be with another, and it didn't satisfy her and this confirms her thought that she belongs with you. Hmm, perhaps a bit too romantic to be true. But still, it's a non-negliable possibility.

Or just get over the fact that she slept with another guy. I had a relationship with a married woman and she was probably doing that guy, too, well she hadn't for over two years, but still she would eventually. Exclusivity in sex can be important, but, important enough to lose your soul over?

If she truly upheaveled your inner life to the point of staring into a endless, senseless abyss of emotional revulsion and steep suffering, then saying: "Hey, as good as the sex is, know what, we can't get back together for serious," is not gonna cut this. Unless you're a pussy.

You asked some very legit questions man. I will have to ponder them over the next couple of days. Just out of curiousity, if you were me, what would your revenge be? I'm not a pussy so I can carry anything out. She ruined me.

It depends on the situation. What are her weak spots? Her vulnerabilities? The people she loves most? Her phobia's and most dreaded nightmares? How can you get away with it? How can you avoid suspicion?

From a personal situation, this chick was pretending to be into me and told me a lot about her colleague, confidential information how she was dissapointed in him, the crazy things that happened to him and how he was a bitch. Later I met both of them together on a party square. Then I chatted up to them in an amiable way, and jokingly told this colleague all these painful facts I knew about him. She stood besides it.

Hey man, Here is a thought... and honestly this is what I have done and would do again without any hesitation.

You say you were with her for 5 years and it was the best 5 years of your life right?
Then take it...she gave you 5 years that you wont forget and then she messed up once.. if you cant forgive her and be with her, just move on and don't plot a revenge. It's harder to move on.

well either way I completely understand the need for revenge, sometimes its the only thing that seems right at the time. But being a bigger man and moving on is the better choice in my book.

Why not try this instead? tell her you are enjoying her right now and that you don't want to change anything. have great sex and also see other people, Or just say you need more time to think about it and just use her.
Win/Win for you in both cases.

If you just want to completely move on then you cannot be friends trust me.

You allow another to rip a piece from your soul and walk away. Someone has to draw the line. Teach society that not everyone can get away with anything.

Bolded is a good point. My ex broke up with me out of the blue a while back, and then wanted to talk...so we had a lot of no strings sex for a few weeks leading to break (I'm a college student). Who knows what'll happen when I head back, since I've been out with a decent number of other girls throughout...but if the sex is good there's no reason to stop enjoying that til you need to. (IMO)

Thanks for the replies guys. I truly appreciate all of them. I understand the need for revenge as well. I mean, I would feel that if I stayed with her that she wouldn't learn her lesson. But maybe doing something terrible isn't needed. Isn't that what karma is for? I'm at a constant battle between telling her to go fuck herself and telling her that I just want to enjoy the sex and see other people. Giving her sex is still giving her pleasure and happiness. Something that I don't really want to give her for much longer.

Let's say I go with the "i want to keep enjoying this but also not be restrained from seeing other people" line. If she says that she won't have sex with me if its not monogomous then I guess I could tell her to go fuck herself? Thay way I cover both bases and everyone is happy (except her )

What do you think?

I would suggest you don't bring up anything. Just have fun until she drops the "what are we line" and then you can have your cake and eat it.

Then you reply with are you having fun? if she says yes
then say something like then I don't get why we have to label it. then enjoy sex

You need to ask yourself a big question.. do you feel like you are going to fall for her again?
if so you need to pull out asap bro, don't put yourself through that again.

Seems good.
