My SO (super long rant. Ignore.)

We’ve been together 3 years and have a two month old son. I️ know his family sucks and he’s had a really rough life between being homeless by himself as a young teenager (13-16 his mother sent him to live with his father because she couldn’t afford him and his father made him live out in a shed for a year and when the shed became unlivable his father made him leave) to being a drug addicted, alcoholic before 18 because his “adoptive” family knew he was naive enough to believe it was completely normal. His whole “family” is drug addicted, living off the government, never worked a day in their life, worthless leaches. He grew up thinking that’s what people are. And finally he saw the light and got clean and started working. Hard. He’s been clean 4 years now but they took their toll on how he speaks to people. Women, children, men, animals, it doesn’t matter. Everyone SHOULD know exactly what he has planned because he said it one time, three days ago. Or he “always” does it this way. Like this morning, we only have one car and he had to be at work at 7 and I️ was going to take him so I️ could get to work at noon without him having to rush here on his lunch break. So at 550 we wake up and I️ realize I️ bled on the bed so I’m cleaning myself up and apparently I️ took too long because when I️ came back out I️ grabbed the car seat and the baby stuff and he got mad and told me it was too late he was leaving as soon as he got finished getting dressed(as he’s putting his belt on.) it was 605 work is 20 minutes away. Maximum 25. I️ don’t like waking the baby up until we’re absolutely leaving because he HATES his car seat and I️ don’t like listening to him screaming. “You SHOULD have already done that! I’m leaving now.” I️ can’t be late to work again. I’m full time and we can’t afford for them to demote me. So I️ said fine will you come get me on your lunch or do I️ need to find a ride? He got loud and said “DUH I’ll come get you!” Mind you our baby is just 10 ft away sleeping. I️ told him he didn’t have to speak to me like I️ was too stupid to comprehend the words coming out of his mouth. I️ told him he was being an asshole I️ literally just woke up and threw some pants on. All I️ did was change my pad and grab the baby’s stuff. “Well then you SHOULD wake up earlier so you can get this shit taken care of! I’m out.” ITS FUCKING 609 and he SWEARS he’s “going to be late” he text me at 633 “made it. Idk why you’re mad I’ve been doing this for two years now!” YES BUT WE DIDNT HAVE A DAMN BABY TWO YEARS AGO DID WE?!?!? I️ try to be understanding I️ really do. He’s just such a dick sometimes I️ don’t get it! He doesn’t think there’s anything wrong with how he speaks to me! And it’s gotten under my skin so much I’m starting to be hateful back and i don’t want to! I️ cant get him to understand it isn’t normal or ok to speak to people like that.
