Am I being crazy?!

So my fiancé is currently out at a bar with his friends and it's almost 2 AM which is the time that bars close in our area! I'm currently 33 weeks and five days pregnant! He usually likes to go out with his friends at least once a week! I don't mind that he likes to go out but we had a conversation that being that I'm so far along I would like him to be home in case something were to happen because at 30 weeks I was diagnosed with ICP which is making my pregnancy now a higher risk! He agreed with me told me that he was done going out and that he was only trying to spend as much time he could with his friends before the baby comes because he claims once the baby is born he is not going to go out anymore! He's a great guy, I never have to worry about money, he has a good job and he works really hard and I truly believe that he is not cheating on me! But tonight he went out despite the conversation we had that I needed him to stay home now and tonight I'm actually really pissed off! He told me he was only going to go out for a little bit this was at 10 PM and if he came home around midnight even I don't think I would be this upset but around midnight he text me to say he was going to another bar and I pretty much haven't heard from him since! The stress that I'm feeling is just not fair I should be asleep right now because I have work in the a.m. yet I'm up waiting for him to come home! Anytime I try to get mad about him spending time with his friends he constantly tells me that I'm being crazy he barely does anything he's with me 24/7 and that I shouldn't be so mad when he wants to go spend time with his friends... all I really want is a compromise of him coming home at a decent time! But I have had this conversation with him over and over and over and over again and it's like the minute he goes out and starts talking to his friends and get to drinking his system it's like everything we talked about just goes right out the window! No I don't want to be a crazy person that makes him feel like he can't do anything so I try my best to keep calm and not bother him.. but he basically lies telling me I'm not gonna be out that late tonight I'm just going to go have one drink when he knows damn well bet he's going to come home when the bars close! He tells me I shouldn't be so mad because every single other thing in our life is perfect but I can't help it this little stupid thing bothers the crap out of me! If the tables were turned I know that he would be 10 times worse than I am so to me it just all seems unfair! I worry that his intentions to stay home after the baby is born is nothing more than just words to make me feel better about the fact that he goes out once a week and I worry that once the baby is born he still going to want to go out once a week with his friends! He says I'm crazy and that he's not but my gut instinct tells me that it's not going to stop! I guess my question is Am I being crazy that he's with me six out of the seven days of the week I mean we live together or am I right to be upset that he always wants to go out to bars once a week! Sidenote it's not always 4 out of the four weeks of the month there is a few times here and there he will skip so I just want to be clear that it's not like every single Friday or every single Saturday it's different days but it seems to be around once a week! Have any of you ladies dealt with this and what have you done?
