Feel like my boyfriend is going to cheat

so me and my boyfriend haven’t done anything since I found out I was pregnant, I am 7 months pregnant and he hasn’t made this pregnancy easy on me at all! Well from the jump this pregnancy itself has been hard on me and my body like right now (tmi) i have a uti and i’m taking medicine for it , my heart rate has been an issue etc., well he knows this and knows I don’t wanna do anything with him because of how he’s been treating me and how i’ve been feeling. Well the other day he was talking about have sex and touching me and practically BEGGING to have sex and it was cringy asf like he kept pushing and saying how he wanted to and it was just ew like made my skin crawl, well then I just gave in and was like fine maybe Sunday but no promises because if i’m not feeling well it’s not happening and i have a freaking uti! so yesterday I wasn’t feeling well and idk how it was brought up but he was talking about sex again and i was like if i’m feeling anything like i’m feeling now it’s not happening and he had an attitude, then he went on to say he don’t even wanna do it anymore and that he went this long without it what’s a little longer and he should know how to control himself and a bunch of other crap, making me feel bad like dude you treated me like crap this ENTIRE pregnancy, i’m exhausted from having to try to take care of myself and our 1 year old by myself, this pregnancy has been hard on me but you’re trying to manipulate me into feeling bad just so you can have sex? then today was the day i said we maybe could but i was finna put our daughter to sleep and i guess he knew it wasn’t gone happen and he started being cold and snarky like “okay whatever ” and was like “i’m finna go smoke” like dude you want sex so bad but didn’t even OFFER to put your own child to sleep. Like I have our girl 24:7 I do the night shift with her and put her down for naps and feed her when I eat. Then 3 days in a row you’ve been smoking but i haven’t had a break in a year 💀 then when I tell him like you take breaks for yourself i’m not going to ask for a break, i shouldn’t have to PERIOD! then he will come in and time will go by and i’ll be like “i didn’t get a break today” and he literally told me “i forgot about you” like yeah clearly. then last night tried to apologize profusely like i don’t accept your apology because at this point you’re playing in my face. like stop apologizing to me if you’re going to continue to do the same thing. how can you forget about someone who complains about needing a break every day. then get mad cause i’m a “bad girlfriend” like you’re being fucking inconsiderate and a bad partner i’m just over itttttttt and he’s been so pushy with sex that i genuinely feel like he might cheat on me
