I had to laugh a tiny bit. Men only mature after they've either finished college or joined the army. Luckily for me, all 18 year old men are drafted here - so all 18 year old boys are turned into 19 year old MEN.
All of my boyfriends have been 19+ (since I was 15), cos I don't waste my time on immature boys who think it's funny to make you feel bad and who only want to bang you.

Men are fully capable of loving a woman, OH so much love! The thing is, only MEN are capable of that - BOYS are not. And being an adult doesn't make you a man by default; I know 35 year olds who are still boys.
I don't know how old your boyfriend is - but unless he's a capitol M-MAN, I wouldn't waste my time on him. But that's just me. If he makes you feel bad, and if you don't get anything from the relationship - dump his sorry a-- and go find another fish.
