Last thursday I broke up with my gf following advice from here, I was fed up of it.

She assumed I cheated and she became distant, i became beta-ized when i tried to prove her i loved her, she cheated and dumped me, i got pissed off and whatevered it. One month later she begged for me to give her another chance, i did, but she was still distant and acting like if I had the fault. When I asked her to go look for proof if I had cheated she said she wouldnt becuse she ''already knew the truth'' (leading me on again?). I tried to think of another way but I got tired of her attitude, and started an argument on how I had always been faithful and she cheated out of her own assumptions. I hate being blamed for something I didnt do. To which she replied ''Deal with it Baby''. I didnt say a thing to that and didnt contact her anymore, she did it knowing the consequences of saying something like that. Anyways, after that, she didnt initiate contact either and we didnt talk for 3 weeks. Later I asked her where she had been and she told me she was ''grounded'' since she still lives at her parent's. Thats when I broke up, I dont like dishonest people and cheap excuses.

Our problems in a nutshell: she thought I cheated so she didnt respect me, I didnt feel like giving her love for that, when I did show her i cared she whatevered it. And altogether after she assumed I cheated the relationship was over. I want to know what could have been done to avoid a situation like that? Was it my fault or hers? What is your opinion on this?

It's her fault. Laws of the world are not an "eye for an eye". She is trash. If she actually cared about you she would have been devastated not jumping onto cocks.

You did the right thing when you broke up with her. Don't put your pride and dignity aside for people who do not respect you.

I'm in a slightly similar situation...not quite the same, but there are some similarities.. I'm not saying this is the case...but sometimes girls will do something wrong...and then they try to blame you...She was cheating on you, so she blamed you for cheating on her..whether you did or not....that was the excuse she made up to justify her actions...You said she's grounded....so that means you guys are probably in high school....Just move on with it dude...Let her make her own reputation...And holler at some of her friends...as the old saying goes "If you catch your girl cheating, fuck all her friends".

"she thought I cheated so she didn't respect me"

thats generally a myth. She may hate you for cheating and break up with you as you cant be trusted, but cheting normally isnt a factor which decreases her respect.

I will say this again. Women's morality is malleable.

She manufactured some bullshit to guilt you, then she goes and actually does the thing she accused you of. That, my friend, is class A trash.

If you believe you became beta-tized, then yeah, you probably could have curbed this behavior but in the end, she is too insecure/crazy/unstable. Something else would have triggered this at some point.

But- I think asking 'what could I have done' is not really useful here. Go forth and find a better one - you deserve it.

You're right. One year passed between she thought I cheated and when she she cheated. So she must have been devastated for that long.
Yeah, youre right, she is still finishing high school. And I think that old saying is wrong, fucking all her friends would be a waste of your time just to hurt her... it makes you loose your value.

I think when you loose your value to a girl's eyes she wont respect you.
She is very unstable and insecure, very hard to handle, but I balanced it with my cool easy going personality. So far I have no regrets of the break up, It was the right thing. ''Go forth and find a better one - you deserve it.'' I needed to hear those words.

"I think when you loose your value to a girl's eyes she wont respect you"

I agree, but losing value is not associated with cheating. Her being mad, hurt, bailing on you for cheating may result but again, its not inheirantly a loos of value. But I don't want to prattle pedantically about a peripheral podunk point.

I disagree... Fucking her friends, if they're good looking, would not be a waste of time.. You're not doing it to hurt her. You're doing it because you can. You broke up with her...Because she cheated on you...You are single..So fucking her friends would make you lose value? I dont think so...If that was the case, this whole PUA community wouldn't exist if fucking girls made a man lose value...I feel that it might make her jealous...but at the same time, line up more girls for you to get it in with..Wrap it up, I don't see how you can lose lol

some women defy the batshit vs beauty scale dude

The saying is about getting revenge ''she cheats, you fuck her friends'', so its a waste of time in that sense. If her friends are hot you're killing two birds with one stone.

LOL

No sir....it is not about her. Look at it like this..Its acceptable to not fuck her friends when you're dating...That would be fucked up. But she cheated on you. You broke up with her. So why would you feel guilty about fucking her friends? It really has nothing to do about her..Its about you being single and available..and the next easiest targets would be her friends..Thats all I'm saying..Its nothing to do with revenge or getting back at her.
