Into it this morning

So me and my dude both started our new jobs today....he work outside and I’m at a store...but anyway so this morning at 715 I got up got my other kids together for school....8am hits and I ask my dude if he gonna call to see if he gotta work so I know if our son had to be dropped off at daycare....so he said his boss told him to call around 9/930....I needed him to call before then cause I had to be at work at 9....He started going off on me so we got into a big argument....I got so fed up cause he thought I was coming at him with attitude and I wasn’t but it’s like he obviously didn’t get that I wanted to be there when our son go off to daycare for the first time....he just kept saying he can take him if he work but I didn’t want that....he pissed me off so bad saying he want a blood test for our son and he don’t think the one I’m pregnant with now is his....before this job I barely walked out the house just stayed in with our baby and slept or watch tv!!! When he said that I just said get out or I’ll call the police and when he went outside to wait on his mom with his stuff...I locked the door....he wanted to come back in cause he forgot his system...I said no cause I didn’t trust him I felt he was gonna put his hands on me!! Now Sunday night we was good I ordered us dinner and payed his phone bill and the next day he calling me all kinda bitches and I’m a drug addict(I stopped everything I use to do cold turkey when me and him got together and never looked back only smoke weed with him)....He actually really hurt my feelings and broke my heart....I love him to death and wanted us to get married....now I’m laying here alone it’s just me and my 4kids and pregnant with my 5th.....I haven’t texted him at all today but kept thinking bout him....I’m just torn idk what to do....part of me wanna stay apart cause we always arguing about dumb shit and he keep disrespecting me but then the other part of me is like try and work us out(he probably wont) and everything will be better cause we both working and we both can now go get our own spot cause I wanna get out my mom house!!! But I really am missing him...I think ima lose my job cause I don’t have the help right here with me and I can’t afford daycare....the lady today only charged me for today and that was my last 40 dollars!!! Idk wat to do anymore!!! SORRY I NEEDED TO VENT
