Well - you really need to talk to him. I'm 24 and I have a very clear picture of what I expect of a relationship. No, I do not have the perfect relationship, but when my boyfriend hurts me, I tell him. Often he doesn't even realise.
I need to tell him what I expect, and how I feel about certain things. The ball is then in his court to make changes or not.

Please remember: You cannot change a person. It's up to them to change. Unfortunately not all things that are nice are good for you. At some stage you need to take stock and decide if it is worth your time pursuing this relationship, or if it is taking too much out of you.
You have posted on this forum that you are unhappy, so maybe consider that this relationship may not be for you.
