Nah. I think she has other things to be worrying about then getting in bed with another man.0
Most Helpful Girl
Why would a guy do that? This means only one of a couple of of situations have occurred.
1. She cheated on you and there is proof.
2. She just recently got knocked up by someone who may still be in her life OR have to be on account of the baby (suuuupppperrrr complicated).
3. She kept it a secret hoping you'd be hooked until she got a little bigger.
4. Things didn't work with the last guy and she may be really bitter about it complicating your relationship.
5. She's looking for a new father to raise her kid and you're it and it may be because you have a bit of money.
I'm sure there is a slight chance love or like is involved, but I can't see any guy going for this outside of a Hollywood movie.1
