Not happy in my relationship (Long story just wanted to rant)

I’ve been with my fiancé since high school and now we’re getting married in 5months I just found out I’m pregnant again with baby #3. Every since he found out he’s been complaining about everything. I asked him if you agree if we keep it or let it go (terminate). He agree to keep it. I always ask him when we found out I’m pregnant. I don’t want him to think I’m trying to trap him. Last night and this morning just pulled me away from him. Last night he was complaining that I asked him to pull the sheets off all the beds so I can wash them. Then he was complaining to me asking me if I’ve seen an aloe ointment for our son that has eczema. I said I haven’t seen and he yells at me saying “wtf you’re lazy and lying your dumb ass seen it you just don’t want to look for it” so I ignore him. I cleaned up the whole house and it’s 2am. I’m getting in the bed and I got some covers.......complaining again. He’s saying “damn you taking all the covers wtf.” I just snap and told him to stfu already you complain more than a bitch in 1 day. Then I told him I hate him cause all he did was tormented me. Then he said get an abortion I don’t want anymore kids from you, you don’t deserve my seeds. And he wants to move on. This man is PMS-ing real bad. I woke up cause my kids were complaining. He’s on the phone didn’t change their pamper and didn’t feed them but took the dog out for a walk and fed him. Wtf I’m drifting away from him. Hey
