Doubts

Is it possible to happily be with someone who holds completely different ideals and beliefs? I'm not saying one is right and one is wrong; these are simply observations. Just trying to clear my head a bit.

I would describe myself as an idealist and a dreamer. I have faith and hope. I have strong ties to family and home.

He seems like a nihilist and a realist. He has no faith. He doesn't have strong family ties and it seems like he can't stay in one place too long.

I thought we were very much alike but now that I think of it, we are two completely different people. We really never have a conflict with our differences, but we are aware of them. I guess we just kind of glide over them. I wouldn't want to go into a conversation about it with him because I have nothing to back up my beliefs. It's just whats truly important to me.
My inner conflict: later on in life, is he going to understand my priorities and be able to compromise even though his priorities are completely different?

Am I dragging this relationship on because he is my first love and I am unable to let go? I have this nagging feeling that although we've been able to hold on to a long distance relationship fairly well, he is going to move away again. If so, whats the point?
I'm anchored to home-to family. Although I did say I was going to study abroad for a semester, it is only for a semester. No matter where I go, I will always come back.
Can I say the same for him?
