You are an awful home wrecker.

don't plan an ultrasound for the same day as his wife's birthday. you are the other woman

That was why you such a person destroy other people's family. Curse you.

I feel bad for you, OP. I may get downvoted for this, but I think that you should further explain your situation. So many people are so quick to judge before they even know the situation. There are so many possibilities within this FML. I absolutely hate cheaters, and I would call you a "homewrecker" but there is nothing that even leads you to that other than peoples assumptions. I can think of multiple things that don't give you that title. Like just finding out and not knowing about it. Either way, you need to tell the wife. She may hate you for it, but it takes two to cheat! Even if you didn't know, it's his sole responsibility to be faithful, and he hasn't been.

Wow. You need to straighten out this situation.

You know he's married and you slept with him anyway and got pregnant....not only is he an asshat, but you are knowingly sleeping with a married man. How would you feel if you were in his wife's shoes? Shame on you

So much of this kind of crap going around.

Did she got for the ultrasound then catch him out for dinner? The fml isn't long enough to understand completely what's going on and ops full story. Come on guys, calm down a bit.

This is when an abortion is necessary. Take care of it then disappear out of his life.

You could become so filthy rich in court.
