I feel like my boyfriend doesn't love me as much as I want him too?

We've been dating on and off again for a year but we just got back together 1/11/11. We immediatley fought when we got together because he'll put that's he's in a relationship on his page, but he'll never put who with. I don't think he's told anyone were together except his guy friends not his girl friends. Whenever I write on his facebook page he deletes it right away. He always comments other girls pictures with stuff like "you're stunning and amazingly beautiful." When we talk he'll sometimes say sweet things like "your the most beautiful girl in the world. i don't love you, I'm in love with you. I really wanna see you baby." We already talked about it and were getting married. He said he's saving up to buy me a ring. Sometimes he doesn't call me everyday or write me on facebook. Our parents won't let us be together because we always used to get in trouble together so he can only come over when he sneaks over, so that's not often. When we together physically is the only time that I feel like he really loves me. When we talk on the phone and facebook I don't. Cus when were together he's constantly kissing me, telling me he loves me, snuggling with me, being so romantic. What should I do? Because everytime he calls or I get on facebook, I just wanna cry. Idk.
