What do i do?

I'm 19 and I've been with my bf for 3 years we've lived together for 1 year. We live in NYC and we are moving to Florida in a year..I was excited and a part of me says is. It's just the longer I live with him it's like he doesn't take responsibility for anything. He plays games all day and when he's off he doesn't pay attention to me unless I tell him to do something with me. Simple things like walking our dog, feeding our reptiles, cleaning their cages is too much for him.. why is it I feel like I'm doing everything ..

Simple..

Cause I am..

We both don't have jobs yet

but I get $200 in child support every 2 weeks and I save it. I pay for all the things we need. You would think he would be more grateful having a gf who takes care of a lot while having no real income.. It worries me moving away from family with him because he still has a child's mentality. I'm tired of asking him for simple things and him getting annoyed when he can wake up at 4am and play games till 9pm.. What should I do? I constantly tell him I don't want to live with someone who is immature or irresponsible and then he assures me by treating me good for a few days but then he goes back to his old ways..We aren't going to break up so if anyone has any other advice..I'm listening please
