Husband is using me

At this point I believe I am wasting my time. Married 7 years and together for 11. Share two boys and I have a daughter (16) from a previous relationship. My problem is I feel that he uses me. He doesn’t work doesn’t clean barely rubs me doesn’t take me out really. He thinks buying me taco dinners and maybe some chic fila is a date. We were separated and decided to work things out this year. I feel like I make a bad move. If I need help with a bill I have to ask. He never ask how much this is or when is it due. Says he doesn’t want to be broke when he gets money because he has no steady income. So he may give me $100 at the most for a car repair or $25 for gas here and there. He doesn’t buy groceries he doesn’t buy household items. He doesn’t go looking for work. He says he’s waiting to hear back from this job since March or April of this year. He makes music all day and smokes weed all day..literally. That’s his entire life. Music/weed. The. He says things like well I’ll just stop making music and smoking around you. Like really? He has epilepsy badly! He has seizures so much from the heavy smoking and up all night and day on his equipment. He says he gonna get disability but never truly does it. He’s 36 and I’m 34. I’m too old for this. I’m tired and feel alone and financially I’m weighed down . I don’t know what to do when he gets upset that I expect more from him as a father and a husband
