Am I wrong for even thinking this..

So I am currently 31 weeks pregnant but my pregnancy is high risk (for the cord falling through my vagina, emergency c section, losing a lot of blood & going into shock after delivery, I am GBS+, babygirl can be still birth, coming out early etc.) I tried explaining to my fiancé many times about the risks on both ends & stuff because he is the type to freak out & he gets really angry when he’s confused etc. so I’m trying to have a serious conversation with him about what can happen & he just cuts me off & engages in another conversation with my sister (we were sitting at the table) I tried letting them finish talking & I brought it up again then they cut me off .. it happened over 5 times. I told them both I’m trying to have a serious conversation but they did it once again so I just shut my mouth & I sat in silence. After a while he asked me why I’m not talking or anything & he got mad because I’m quite .. I’m really upset how i’m trying to have a conversation with him about our daughters health & mine & what could happen. I am now debating if I even want him in the labor room .. we went to L&D a few times due to early contractions .. so I got a preview how it will be with him🙄he just puts movies on that he likes & stays on his phone. He complains how he wants to leave & how he’s hungry.. so I can only imagine when actual labor happens. He also has mental health problems like schizoaffective & he has seizures. Idk how I can help him while being in labor .. he takes medicine which helps a lot but once it hits 8PM he starts having episodes .. my Mother is super supportive she helps me calm myself down & talks to me about good stuff & how L&D will be perfect etc.. is it wrong I’m thinking about just not letting my fiancé in the room.?🤦🏻‍♀️& letting my Mom be my support .. I feel like he deserves to see his child being born but I know I’m going to need support & someone who knows exactly what’s going on & can make choices etc. I feel so broken that I am even having thoughts of my partner not being in the room simply because he isn’t supportive & he ignores me etc.. also last night I kept waking up & I was really thirsty & I had to use the bathroom.. when I woke up he woke up & asked if I was okay.. I said yeah i’m okay I’m just thirsty & I need to use the bathroom. He asked me if he could help or anything & I asked him if he could get me a cup of water.. he was quite for a moment then he exhaled deep ( because he got irritated) then I said “nvm I’ll just get it myself) 🙄🤦🏻‍♀️honestly I’m at the point idk what to do
