SO mad because i dont want to be sexual.

I just had a baby she is 10 days old. Me and her dad moved in together as soon as I found out I was pregnant. Well since about 3 days ago he has been trying to be sexual and I turn him down because I literally just had a baby when I turn him down he gets PIST this is a 30 yo man I'm speaking of. Last night he said since I can't have sex if I can give him head I told him I was tired because i always get up with our daughter while I let him sleep. He got bad literally took my blankets away from me and wouldn't let me lay on the bed he was spread all over smh telling me I can be cold since I'm a cold bitch for not wanting to give him head. 😐😐😐 Anyways I finally just went to sleep with no blanket and today is a new day well he came home from work and automatically started to get some weed ready for him to smoke after I told him when I bought baby home to not smoke if he is going to be around her and how anything can happen and I might need him etc smh he didn't care and just told me fuck you and went outside. He didn't even see his daughter when he came home showed her no attention just his pipe to smoke smh all over me not wanting to be sexual? He don't change diapers he don't make bottles all he does is hold her for maybe 10 min at a time during the weekend when he's off and I feel he is disrespecting us both by smoking that shit knowing she's so young and anything can happen. What should I do? I know this isn't normal behavior and he never acted this way until I turned down sex of course.
