My wife gave birth to a (biracial)baby that clearly isn't mine, and I'm divorcing her. But I'm worried about the relationship between my two kids and their new half-sister.

A month ago, my wife gave birth to a baby girl. But after looking at the baby, I just knew something was wrong. The baby was obviously mixed-race, and very clearly not mine. <br><br>I am white, my wife is white, and we have two children together who are obviously both mine. And this new baby, was clearly biracial and not mine. After doing a paternity test, my fears were confirmed. <br><br>The baby was not mine. It was very hard to take in, and it took a lot of restraint not to blow up at my wife. In the end, I managed to have a (more or less) calm conversation with her about it. She confessed to having an affair, and said she fell in love with the guy and wanted to be with him. I told her I'm divorcing her, and she said she understood.<br><br>It's been rough these past few weeks. I am still hurting, and I have felt lots of anger and sadness. But I know I need to take care of myself and also my kids. They don't deserve their childhood cut short because of their mother's infidelity.<br><br>However, there is one thing that I can't stop thinking about. And that is the baby's relationship with our kids. Our kids(ages 6 and 8) both love their little sister and are unawre that I'm divorcing their mother. They will probably find out soon though, as the divorce process begins.<br><br>What I worry about is whether the baby's mixed race would cause any problems in the future, when the kids are older. I grew up in an area that was very diverse, but my wife grew up in an area that was almost all white. I know she comes from some racist stock, and I have heard her make prejudiced remarks about hispanic people and black people, though always politely and in a "I'm not racist, but" kind of way. I am worried that as the kids grow older, they might inherit their mother's racist sentiments. And if they do, would they take it out on their half-sister? <br><br>I have spoken with my lawyer about getting full custody of my two kids, but said it would be a difficult case to win. My wife doesn't do drugs and is stable Mindet and determined, rational and calm person. While I am the complete opposite. I am bipolar, and have been prescribed anti-psychotics for it. I also drink regularly, and have tried doing drugs before(though I haven't done them in years).<br><br>I am worried that the judge would see me as the unstable parent, and that my wife's affair would be seen as a normal marriage slip up.<br><br>I am not racist, and love all people. And I would never allowances racism in my house, or with my kids. But in the event that I only get partial custody, do you think my kids would inherit their mothers' racism? And would that be a problem as they grow older?
