Delivery Room

So... Since I found out I was pregnant I always thought I would want my boyfriend, my mom and sister in the room with me when I deliver. And when I found out three months ago, my boyfriends mom mentioned to him about wanting to be in the delivery room and I thought about it and thought that was fine. But now where I'm closer and everything's starting to hit me I've really thought about all of this lately and I just want my mom and him in the room when I'm giving birth. So, last night I brought this up to my boyfriend and telling him how I felt, and I said I only want you and my mom in there and I don't want to offend anyone but it's just a very personal and intimate moment and I'm going to feel uncomfortable with everyone in there seeing me push a baby out. And so on, and he said he felt his mom deserved to be in the room more than my sister. And that really pissed me off and upset me, and I told him no she doesn't and if I wanted an extra person I would choose my sister. And I told him that I didn't care what anyone thought, it's me giving birth and I just want him and my mom in the room. And then we got into a fight about it.. And then he later texted me saying he didn't care who was in the room and I should have whoever I want, he was just mad because I didn't ask his opinion and so forth meanwhile him (being in the other room) texting me and I just went to bed lol. I just had to vent even though I've talked to my family about this today and didn't know if this has happened with anyone else.
