Does he love me or my body?

I have a little problem with my boyfriend that I would rather discuss anonymously here. It's about the question of whether he is really in love with me or just wants my body.

We've been together for five months now, so I've had enough time to think about the problem. On the one hand, he tries to seduce me at every opportunity, even if he actually should know that I just do not want to (eg because I have other problems that moment). On the other hand, somehow he never wants to do anything else with me. He never has his own ideas, when we meet and when not sleep together we only watch TV or DVDs all the time. That can not be everything?!

That's why I wonder if he just uses me to satisfy his hunger for s** and I do not care about him otherwise. If he was more interested in me, he would rather want to do something with me and we would like to have a good time, I think.
