With my ex but not

So I’m talking BACK to my ex. We been talking for like 6 months now. I’m over it to be honest. I wanted to be with him but every time I mention it, he says “I Don’t want to be in a relationship but I’m committed to only you.” He wants to have sex as much as he wants, of course. I’m just not feeling it because we been talking for so long and haven’t made anything official. We don’t go out, he doesn’t have a job, so if we go out, I’ll be paying. I literally sit in his house all day M-W until I get my son from school. Thurs-Sun I work days. So Thursday I get off, get my son, Friday he goes with his dad. So fri-Sun I’m at his house after work. We don’t do shit. Just sit there. Idk.I think I’m asking for too much. What would you do?
