I'm afraid you only have two options left: accepting he won't change and live with it, or moving on and waiting for someone who will show you he loves and adores you.

If you talked about it so much, and he still doesn't get it...I don't know. Sometimes love isn't enough, or in his words: "liking". I mean, i can understand after 6 months (you're together for 6 months right?) he's not ready to say he loves you, but he could show you, couldn't he? Even just saying he's falling in love with you, or showing he loves you.
Love, to me, means that amongst other things, you care about that person and want to see them happy. Not: "deal with it by yourself". I don't even talk to my friends that way.

What I would do if I were you?
Talk to him about it one last time. Write it down before you'll talk, so you can tell everything that's on your mind, otherwise after you had the talk, you can think of some other things that you wanted to say but didn't say cuz you didn't think about it at the time. If he just says: babe, I'm not gonna change, bla bla bla. Then sorry, but I deserve to be treated like a girlfriend. If a guy doesn't treat me the way I wanna be treated, I'm sorry, but he can leave.
You can always have moments you're like: wtf? what are u doing?
But if that are just a couple of moments, it's fine. It's when you get that thought every week or more that something isn't right.

We can't tell you what you have to do, only what we would do in your situation.
Good luck!
