So I've been dating a guy for 3 years. I really love him and care about him. But some of the things he does really bother me and worry me about our future. (Smoking sigarettes, staying up all night and sleeping all day, not working out and eating healthy) I've talked to him about it but he doesn't seem like he wants to change him habits. If he keeps doing those things I don't see a future for us. What should I do about it?? Comments would help !
