My wife [32f] gave birth to a (black)baby that we both knew wasn't mine and I [m35] playable rolled and she's starting to think that I knew the baby wasn't mine all along

Our relationship was a bit rocky before the covid and it only got worse when we were expecting to spend months in lockdown together. My wife started getting distant from me and I confronted her and eventually found out it was because she had met someone else and she wanted a divorce. <br><br>She was 5 months pregnant at the time and she told me that while she wanted the divorce, she didn't want to break up the family and so she offered for us to stay together as friends/co-parents until the baby was about 1-2 years old. She said that the reason for this was that she wanted our kid to have both parents around even if it was in the same house. I agreed to this and thanked her for being considerate of our baby. <br><br>I think at this time, she also told me that she had hooked up with another guy a few times and she was fairly certain that she was still pregnant with my kid but I don't really remember that part too well. <br><br>Anyway, we went through the rest of the pregnancy together and our baby was born in December. A few days after she gave birth, I noticed that the baby was black while both my wife and I are white. I played it cool and didn't mention anything and just enjoyed me first few days as a father. <br><br>When my wife was alone with me, she told me not to worry, that she really couldn't control who she wanted to hook up with and it was just sex anyway and she loved me and our family. She thanked me for not blowing up at her for bringing this baby into the world. <br><br>Well, I'm not sure whether I'm doing the right thing or the wrong thing, but ever since then I've just gone on with my life as normal. Shit might get awkward when our baby grows up and notices that she doesn't look like us but I honestly don't really care what my wife does any more. I guess I just want her to think that I'm a good guy for not calling her out on her infidelity. Maybe I've just given up on the marriage. <br><br>But the problem is, my wife's recently been hinting that I might have known that the baby wasn't mine all along. Not in a mean way, but I can tell that's what she thinks. And It's just making me feel like I'm losing any semblance of self-respect, and I know I'll feel worse if she ever finds out that I knew that the baby wasn't mine.
