My wife gave birth to a (black)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 black baby girl. We're both white, so she was forced to admit that the child was a result of a one night stand last year. <br><br>I've started divorce proceedings, although we're still living together for now. Between our two boys(aged 2 and 4), and my wife and I having been married for 6 years, the house is still filled with pictures of both our kids showing them as mine. I'm planning on taking down all those pictures, but I'm worried about the adjustment the boys will have to make when they'll see how the house doesn't reflect them anymore. Every single picture will now either have to be taken down or be about her alone.<br><br>What can I do to make this as easy as possible for them? And what can I do to prevent them from realising that I've realized that she lied to me about their birth? We had a conversation in which I told her that we'll have to take down all the pictures and craddle of their shared room, and she said she could wait a bit longer, but I said that we have to do it as soon as possible so we can start with our Promised Separation.<br><br>Another thing is that the two boys have a younger black half-sister (aged 1). She's legaly my wife's daughter, since she's still married, but we both know that she's the result of her wife's infidelity. What should I do to explain to the boys that the little girl isn't their sister?<br><br>Finally, how much should I tell the boy's father? My wife's infidelity is his business, but should I tell him that she lied about the genders and races of the kids she's had extramarital aveneles? Their relationship is basically dead since they haven't spoken to each other in about 5 years, but I still want to know if I should tell him.<br><br>I know this is a lot of questions, but I could really use some help. I would also love to know if I'm really going to divorce her or if I should try to aruge with her. <br><br>**
