Why are these people such idiots? Be mad at your goddamn partner for being a cheating bastard instead.

She met the guy online. She probably doesn't know anything about him, except what he tells her. So if he says he's single, how is she to know that he's actually in a relationship and expecting a baby? It's the guy's fault for being a lying son of a bitch, not her fault for "stealing" a guy who conveniently forgot to tell her he's married. FYL for having been fooled by such a dick.

Internet dating always end up with someone sobbing.

i agree, she had no idea he was married, let alone expecting a child! i dont get these women (or men) who are mad at the other girl/guy their significant other is cheating on them with. GO KICK YOUR HUSBANDS ASS! the only time you should beat the bitch is when she knew you existed, otherwise get someone who respects you. fucking IDIOTS.

I wouldve went to her house and beaten her with a bat

Exactly. OP totally deserved this one.

i don't think thats a good idea, that woman is pregnant, she now has the strength, and intelligence of a woman and a small child, not to mention an extra set of nails.

it is f HER life dumbfuck how the hell is she supposed to know the guy is a lying cheating asswipe?

Her life sucks but she doesn't have to deal with her husband cheating on her while she is pregnant

Seriously... only one of the two people she could be pissed at is likely to take care of her. It makes sense for her to be mad at the other woman - she stands more of a chance of scaring her off and keeping her (cheating jerk of a) man nearby to take care of her and their baby.

If he's cheating now then he's probably going to end up leaving her and their child high and dry anyway.

I don't know the details of this situation from the FML, but maybe the pregnant woman just wanted to scare away the other woman because she needed the man to help her take care of the baby. Otherwise, if the woman wasn't pregnant and still took it out on OP, that would be foolish.
