advice please!

Alright... this is what's going on, I need to let it out before I go nuts. So I met my "boyfriend" exactly 15 days ago.. we liked each other.. we saw potential on each other and we decided to start dating... moving on.. we never had a first date, our first 4 days together I slept over his mom place and he was cooking for me, buying food with his food stamps. When he got paid he spent all his check buying himself unnecessary shit.. yes I'm grateful he bought me a 25$ VS gift card.. but he didn't even had the detail to take out for dinner... he could've spent 30$ on me and I would understand he got other things to do with his money. So when his mom came back.. a few days later they got into an argument and his mom told me take him with u because I don't want him here...so like a dumbass I took him to my place 😡 he has been staying with me to this day.. we have been arguing a lot lately,. He thinks I have to drive him and pick him up from work all the time... he got me fucked up. Sooo today out of nowhere he told he was going to buy a tv for his mom house.. mind u that his mom don't want him there anymore and she doesn't want him to use her tvs for him to be on his PS4 all day... so I laughed and I told him u are stupid because I know his mom is going to trip about the light bill. I'm fucking annoyed, I'm a bitch.. I have high expectations and this is not what I deserve. I know my worth and it seems like I can't let him go.. I'm so used to be with him that I don't know what to do 😔 help please
