<human>: Can you provide a brief overview of the text?

Yesterday my boyfriend of 2mo told me that he has a son and is married. He and his wife are separated and had been since January. They were only married for two months before she became pregnant and left. He is in the process of finishing the divorce, I've seen the paperwork but I'm very floored.
 I feel like our relationship has been inappropriate since he is still legally married. I've never been married and have no children, honestly this whole situation makes me feel like a kid myself. He says he withheld telling me because he wanted to make sure I would be accepting and loving of his son, which I find understandable. However, he hasn't requested a paternity test and the way that marriage sounded I can't understand why he hasn't yet.  He says he will so that's...that. I don't mind that he has a child, however me being new to this is very confusing. 
His wife wants him to sign over all paternity rights and he says he won't see his son unless she let's him and has said she will let him if he pays for everything his son needs. On my side of things I have asked for our relationship to be on hold until the divorce is final, I'm just wondering if I'm too young and inexperienced for this entire situation?
<bot>: My boyfriend is married with a child and withheld telling me about it until now, I don't know how to react.
