Feel as if he's starting to pull away?

I think that if he is really in to you, he wouldn't be able to get enough of you. It's true that some people, both guys and girls, enter a relationship with good intentions but continue because they enjoy the ual time spent together, not the companionship. Ask him what's up. Do it face to face, you should know where your relationship is headed by the way he handles the answer. Beware, some people are very "smooth."
