OP, don't beat yourself over this! Some people want to have their cake, drop it and smear it on the floor and then look good for picking and eating it like nothing happened. You deserve someone better.

be happy she's gone op if she won't accept what she did was wrong and hurt you she ain't worth the time and energy

That's not okay. And she can't use ****-shaming as an excuse for cheating. That's ******* dumb. It'd be different if she was single but she's not.

She SHOULD be ****-shamed, because that's exactly what she is. A filthy little scumbag ***** who deserves to be alone for the rest of her pathetic life. In fact; as revenge, let everyone know exactly what she is. No loyal person deserves her. And your 'Friend'? a backstabbing low-life ******** who needs to be backhanded, hard, multiple times.

I think slutshaming can be a very bad thing. It can mean that what guys get praised for, girls get hatred for. But cheating is never good.

She keeps using that word. I don't think it means what she thinks it means. (For the uninformed, "**** shaming" is degrading a woman just for having a lot of consensual sex with willing partners, whereas a man wouldn't be, or would even be praised. What this girl is describing is "being unfaithful in a committed relationship".)

A poly relationship only works if BOTH partners are aware it's poly.

I find it hilarious how people think there's always a excuse for cheating...Like you're forced to do it or something like that.

Oh my god your girlfriend need to give her head a good shake she's the one that cheats on you and tries to make you look like the bad one

Did she really call herself a **** and that you were 'shaming' her? She put the shame on herself! Awesome reason to get out guilt-free and put the blame on you. FYL OP.
