help.. In need of some comfort

my husband and I have been TTC and we just found out that he had a son with his ex and he is currently away from me dealing with a lot of issues of Courts right now and I've had a suspicion that I might be pregnant of course I have not told him that but when he caught me in the bathroom he said please don't be pregnant. I haven't checked a test yet because it supposedly my. Supposed to be in two days and I want to wait but he's texting me about his son and how he's my stepson because I'm his wife and how he's telling me that this is his chance prove that he still a good father and I'm here sitting and thinking I don't like this what about me and everytime I try to talk to him about it he just completely tells me to stop. I understand that this is his son told me he wanted for a while I guess I'm just hurt that it's not with me. maybe I'm just being sensitive and a jerk but I just really really want to have my family with him and I don't know if he wants it right now
