I feel like I failed at being a wife

So I’m 28 wks pregnant and pregnancy has been really hard after doctors telling me three months before I got pregnant I’d never have a baby due to cysts the sizes of oranges on my ovaries and some other problems we were so scared we would miscarry which just stressed us out then after we were in clear my hubby and I just can not have sex at all like I am dry and when we use lube our son pushes down on me so hard he can see him and it so painful we just don’t have sex and I’m willing to endure it just so my husband is satisfied like that’s my job and he refuses to even touch it got so bad he won’t even kiss me I thought he was having an affair but in all reality he won’t kiss me or even shower with me or touch me and shuts me down at any time I try to have sex with him because he’s been jacking off and finally came clean to me I feel like I totally failed like I’ve offered to just suck him up until he came like all I care about is that I’m able to please him but I’m not and he don’t want me to what do I do to fix it 😭😩
