Hi everyone, i have a problem, my girlfriend cheat me. We are in relationship for few years, and i am not the faithful guy, but she doesn't know that becouse she never caught me. But i caught her few months ago...i would be hypocrit if i broke up with her, because i was doing it to...But now i am in emotional hell...i cant concentrate...i am depressed and so...i can't work, i keep thinking about her, and when i am not on work i try to be with her all the time and i act like a dog...she has psychological power over me...and i hate it! How to turn that around? How to make her addicted to me again, like she was before?

Karma's a bitch isn't it?
Sorry to bring it to you - I think you don't deserve any help. If you had some balls, you would be in an open relationship with her instead of cheating... Now you are crying about something you have done to her more than once. I wouldn't be surprised if she knew

This is a place where people come to get help. Period.
At OP: cut all ties with her if you're emotionally invested in her. Most likely she will cheat again. Your energy is always better spent in a new relationship
If you're not too much into her, keep her as a FWB.

I too am a former cheater, so I won't beat the OP that bad.

You're in emotional hell because you haven't accepted the fact that you hurt her just as bad as she hurt you right now.

My advice to you is this, tell her what you know about her cheating, and tell her about your own. Cheating is usually a sign that something is missing. Since you both are doing it, it's highly likely neither of you is getting all you want. Being honest with her makes the tables fair. From there you can decide if you want to determine what was missing that caused you both to seek stuff outside the relationship and figure out a way to make it better, or if you want to walk away now.

The other alternative, as suggested, is to recognize that you're already in an open relationship, and you can continue that way with the only new development being you both know it's an open relationship. But the way that it all came about, I'm doubtful this will work for you.

NEXT her, don't be to weak to stay with a girl whose done you wrong because chances are she'll do it again.

I support this opinion. IF you want to save the relationship (which is not the only or the best option here) you should admit your own cheating from the past. That way you'll be "even" (assuming you do feel even with her) and you won't be the "begging jealous partner", no, suddenly you'll have common ground. You both weren't as invested in the relationship as you thought you were. Your point seems to be that this was a mistake and you should have been faithful. If she thinks about her own part in it the same way you might actually have a chance to move on from this.

Word of warning, if you don't confess your own cheating that means even if she gets her shit back together (for a while) there's still going to be that disconnect between you two. And guess what, that disconnect is the reason for BOTH of your cheating. Slapping a patch on this won't work, you need to "start over".

Mates, your advice to the OP is to tell his gf he cheated too and try to make things work? Really? Why?

You must understand that men and women cheat for very different reasons: guys cheat because we are wired to spread our seed in every female. How many of you fucked a woman without being in love with her? Yap, most of you, I guess. You have sex with her and then forget all about her. Guys will cheat mostly in the spur of the moment, women are emotionally invested when they cheat.

To elaborate a bit more: women will cheat on you only if they perceive another guy more alpha than you. Hypergamy. There's no other reason why a woman would cheat on you. You might say women do, sometimes, cheat out of resentment but even then, they will still look for somebody who's a better prospect than you.

Do not condone cheating. Ever. She cheats, she's gone. Cheating is ALWAYS a sign she's not GF material. Savy?
