No connection anymore

My husband and I were so excited to have a baby and had been wanting one for a while but now that we finally got pregnant, a lot of things have changed. My hormones have boosted my sex drive and orgasms through the roof so I’m constantly craving sex but now that I’m 7 months, we only have sex 3-4x per week. We lost our connection and I feel as though we’re just friends or like, roommates. We don’t talk like we used to, our sex isn’t what it was even a month ago, we fight constantly about petty things, he doesn’t make me feel beautiful anymore and I’ve got this growing belly now which brings on insecurity. I love my belly and this baby so much and my mom always emphasized that men are babies too and we need to constantly remind them how much we love and appreciate them so they feel included. With that being said, I cook all of my husbands meals, clean the house, still work full time, call and message him throughout the day, but he’s become so distant that it’s hard. He doesn’t appreciate the things I do anymore and I don’t need him to but he expects them still and this is why I feel as if we’re just roommates. He came home the other day and I had all the lights off, candles lit throughout the house and all around the tub, a cheese plate set up, and lingerie on for him and still NO SEX. He just ate and went to bed. He doesn’t call me throughout the day and when I call him to ask how his day is going, he’s short and doesn’t ask me. He hasn’t massaged me throughout my pregnancy, gone the extra mile, and I’m fine with that; I’m independent and can handle not being babied. What I can’t handle is this distance that has formed. Idk what caused it, idk how to fix it, idk what it is. He’s not cheating on me and I asked him if he thought I was attractive still and he said yes but there is no connection. I don’t feel a connection on my end either but I’m trying and I have my needs (not to sound like some crazed sex freak). Does anyone else feel this way?? I want to have lots of fun sex before the baby gets here and I want to love and be loved by my husband like we used to. I feel like I’m doing my part in putting in 100% towards our relationship but he’s not putting in on his end. Do I sound crazy? Am I overthinking this or being dramatic? Plz help
