At a loss

My boyfriend complains that Ill take a bath and then go to bed early every night. Im 21 weeks pregnant and its relief for my feet and lower back soaking in the bath. He always says I dont want to spend time with him when every time we "spend time together" its him watching a tv show he likes and me bored on my phone and we hardly talk at all or when we do he is on his phone and Im repeating myself or being interrupted to look at a meme or video. Ive tried telling him thats not spending time together to me at all so many times andnit turns into an argument of " a pissy fine what do you want to do" or I want to relax after work. He works like 7 hour days doing carpentery, I work 10.5 hour days at a hospital pharmacy and walk a minimum of 4 miles a day and am on my feet all day. We have hardly any sex life anymore. He never wants to have sex and whenever Id ask before he would saynit upset him that I pressure him into it when Id joking say something because its like a once or twice a month thing and has been since before we got pregnant. I told him last night I stopped asking because it never happened. Or id tell him I want it and hed say that sucks. I love him honestly ita just those things bothering me in the moment and talking about it is a repeat cycle and we will have the same conversation in like a month.
