My son had this experience recently. Except that it was her accusing him of cheating, not someone else telling her. It was all a big show to take the focus off her dumping him for her violent ex. She did the big Facebook tell all shame thing too. So I'm always suspicious when someone goes to social media straight up to publicise what should be private anyway, without verifying facts. It seems it can just be to cover up what they've done, or are about to do.

Don't need someone who doesn't ask you for the truth. Personal thing, someone told me she had a baby by my boyfriend. I confronted him about it. He was still a virgin. We are married now. You ASK people and TRUST.

Just wait, sooner or later, she's gonna start complaining about being single and questioning why she's single.

That's why I don't like using Fb much. All I see is drama.

Buy her a trampoline since she likes so much to jump to conclusions.

I hate when people turn to social media and write horrible things about a person. It's so immature. Hope you get things sorted OP.

Typical women always trying to find the bad in ppl this is why I'm done with human companionship

I hope you commented on the post with something like, 'first I've heard of it. If you'd talked to me before posting I might have had a chance to tell you it's not true.'

Doesn't sound like the kind of person who'd believe you anyways if you discussed it.

She should to talk with you first so bad girlfriend
