It's easy to get caught up in the romance (for lack of a better word) of it all and overlook things that, at the time, don't seem like that big a deal. The thing is though, the farther along you go in the relationship, the more those things become bigger factors and can cause problems, but by then, you are so invested emotionally, that you are afraid to let go. I think it's great that you are questioning these things now, before you get too emotionally invested. Like they say...an ounce of prevention is worth a pound of cure.
