I don't feel sexy anymore 😔

So I'm 26 week and 5 days pregnant I've put on 20 pounds so far during this pregnancy and I just feel huge. I try to be as sexy as possible for my fiancé but I don't think it's working. He's been so emotionally and physically shut down and it makes me feel even worst. I feel alone in this pregnancy with our first son he was always at every appts and always rubbing my stomach and always kissing me up and sex was great but this time around its just awkward 😔. He has made no appts, he's working even more now and when he gets in he's sleeping even though I massage him and everything to make him feel relaxed when he gets home. Idk what to do, he has no time to pick a theme with me look at baby stuff nothing I just feel like we're falling apart or maybe it's just me and this pregnancy. I just needed to vent a lil. Hope everyone has a bless day 😘
