So this LTR I've been seeing for ~ 6 months first got together with me a few weeks after she found out her now-ex (2 year relationship) was cheating on her with his babymomma for 1 1/2 years. The guy had been going crazy trying to contact her and she changed her number and blocked him on Facebook.

She has always talked alot of shit about him, which I always felt was just her still having feelings for him. Well, last week he made a fake Facebook imitating one of her male friends that doesn't use Facebook (wtf?) and she added him and he started posting stuff on his wall like 'how do you talk to someone who has hated you for 7 months?' She deleted him when she found out it was him, and told me about it 2 days ago.

Today I checked her Facebook and saw that she added her ex's actual profile, presumably yesterday. She did not tell me. That night we did anal for the first time (by my urging) so idk if I should outright dump her or force her to show me her messages or ignore it or what. Obviously this needs to be addressed.

Edit:Well, I was waiting for her when she got off work. She didn't know I would be there. I brought all of her stuff in a bag, prepared to dump her.

She acted totally confused, and said she never added him. I showed her her Facebook and searched his name, and of course he was there. She insisted she didn't add him, and said it might of been her sister who uses her computer and she often leaves her Facebook open. It sounded like the dumbest shit I'd ever heard, but she showed me her messages, and the last one from him was from when they broke up. She showed me her texts and her call log / contacts and there was nothing. Her recent activity showed he was added 5 days ago. Plenty of time to communicate if they were going to.

She appeared convincing and forthcoming, and she did tell me about the fake profile incident which wouldn't of made sense if he was already on her friend list. Overall I don't know what to think. I've heard of Facebook sending out friend requests without your permission so I guess it is plausible that this could have happened... I ended up forgiving her so I could take her ass again.
