Menewsha Avatar Community - Help with my situation, please.

My boyfriend frustrates me. He doesn't spend as much time with me as I would like. He would spend every other weekend over at my house, sleep with me which he thinks is enough to make me happy, watch a dvd and then go home. He doesn't even pay that much attention to me when he's here. We used to be really sweet before he started school. We talked about our future together and marriage which we already planned to do twice before but he cancelled both times because he didn't know how to say it to my father and that we don't have the money for it yet. And now we're planning again in 2 years. Also, his idea of a wedding is just a civil wedding with cheap-o wedding rings. His budget for the whole thing is less than $1000, including the dinner/reception after. And he's expecting me to pitch in for half of that. No engagement rings, either. I agreed to this because I love him so much and I just want to be with him but now I'm thinking twice about it 'coz does that mean, I'm just worth that much to him?
He is in school but I don't think he really likes it. He's always late for his classes
and do his homework and projects at the last minute or not at all. He doesn't even txt me or call me that much 'coz he's always taking a nap. When I tell him that school is taking up all of his time that he don't even have time to call me, he says it's for our future. But he doesn't have any ambition except to teach 'till he's 60. We're not getting along with that because I want more. I'm don't plan on working as an employee for my whole life. I want to travel the world and
start my own business and I want him with me but he's not really for it. It always lead to arguments because he would say that his ambition is not enough for me because he wouldn't be able to buy me makeups, clothes, etc.
But my point is not that at all. For me, It's just that life is becoming so expensive these days that just a teaching job wouldn't cover everything.
He is kind of materialistic too and I think about that. He always scoffs at me when I window shop and point out shoes and clothes that I like but borrowed $200 from me to buy a bag and he hasn't paid me back a cent yet. I mean, I wouldn't
even spend that much for a material thing and he's saying I'm materialistic.
I'm also becoming unsatisfied with our relationship because he doesn't really give
me gifts, we never had a decent date where I don't pay for half of our dinner or paid for our movie tickets. Sometimes I even pay for the whole thing even for our fare.
Most of the time, he only spends for our fare and he complains that our dates are really expensive.
He also doesn't respect my privacy that much. He always tells his friends what I do. While I may take that as him just being
really proud about me, I don't appreciate it. I'm a very private person and I don't want the whole world to know what I've been up to.
There is facebook for that. I've told him about it and he doesn't think it's a big deal.
We've just been arguing a lot lately 'coz I've been really bitchy towards him. Is it wrong for me to ask for his time and attention?

I'm thinking about breaking up with him but I love him so much! I don't know what I should do.

Should wait around for him? Am I on the wrong? Am I too demanding. Or should I really just move on.

I can't think straight about this right now so I need help, please.

Sorry for being too long but I hope someone would have the patience to read this and advice me.

Thank you
