Question about sex and relationships

Queen

So I'm 24 wks pregnant and me and my partner we don't have the same relationship we used to have before we had kids etc we have a 1 year old already and have a son on the way and he isn't the same with me anymore we cuddle and that's about it I mean dang he did knock me up we haven't had any sex in months and it's hard for me stressing me the hell out. Anyone else have this problem. It sucks . I don't see how he knocked me up now he isn't the same with me . Our relationship doesn't feel like a relationship anymore . :'(((
