Long time reader, first time poster. Sorry if it's a bit long. So it's a complicated one. We found out after my baby was born that she isn't my boyfriends. She's from a one night stand I had during a short breakup in our relationship. Unfortunately I believed all through the pregnancy that it was BFs so didn't say anything until I realized when she was born. I had used contraception with this guy and thought there was no way it could be his, but baby looks like him and nothing like BF. We've had massive arguments as you can imagine, and it's all my fault for not being honest in the first place. But we keep coming back to the fact that we love each other and we are both just so sad and disappointed that we don't have the family we thought we would have. We love the LO of course but when I look at her she reminds me of the other guy, and he can't look at her as his own, even though he spent 9 months waiting for her. I'm surprised he's still with me tbh. It's driving us both mad inside and we haven't been able to talk about it properly yet. No one else really knows. I want to know if there are fathers out there who have taken on someone else's baby as their own from birth, and how everyone coped with it, or not?
