Be careful what you wish!

Me and my bf had a stupid fight about him wanting to go out. We are trying for a baby, we are both 29. I feel like at this stage of his life going out should just not be a priority. However we have been having a four day long argument about it. He clearly can’t see my side and I guess I’m not seeing his. I don’t get the big deal of wanting to go out? Clubs/bars what’s out there??? He says he won’t let me ruin his social life??? He sees his friends and he’s always over his brothers or his cousins house. I feel like he is not mature enough to see the bigger picture but one day maybe he might. I’m so hurt because he would pick having a (social life) instead of being with me! I told him to be careful what he wishes for because he’s saying this won’t work, expecting me to try to convince myself to stay here it won’t happen. Any advice? Am I wrong for not wanting him to go? Like am I tripping??? Thank god I didn’t have a baby with this man I would be an emotional wreck.
