I'm looking for advice. No judgement, please. My wife and I have been married for seven years. We have been in an open relationship for a while. There is a regular guy my wife hooks up with. We'll call him Steve. Steve has grown to become a close friend and someone we can rely on when times are tough. He hooks up with my wife twice a week.

Well, now my wife is pregnant and it's most certainly Steve's. Due to an injury, I haven't had sex with my wife in nearly four months. During this time, she had more contact with Steve. We had agreed early on that if she were to get pregnant by another partner, she would abort. But her urge to be a mother has kicked in and she wants to keep the baby.

I have really mixed feelings on this. I know biology doesn't matter when it comes to family as my brother is adopted. But I kind of accepted we weren't going to have kids. I mean, I wanted them but she was always putting it off as she just wanted to focus on her career and have fun. Now we are going to have a kid and it isn't mine. I feel I've been cheated out of something.

I explained this to my wife and she thinks I'm just overthinking it. She said this is the family we have been dreaming of and that we can try for another baby in the next two years as she definitely wants a second child. She doesn't want to tell Steve because she doesn't see the child as his but mine. She sees it as no different than if we had used a sperm donor. She keeps saying I'll be a good dad and fall in love with the baby when it gets here. But I really don't know.
