Somewhere between a rock and confusion

A few years ago I saw an edited version of the movie, When Harry Met Sally. One of the main themes behind the movie is that men and women can never be friends because they end up falling in love. I have never found this to be true. I have had many guy friends and proven this to be wrong, until now. I'm not sure what to call it but I have been sort of dating/talking to this guy that I met a while ago. It was way too on and off and confusing for me, for example he told me that he likes me and is interested in me and then doesn't call me for a week. So I told him I was tired of being confused and he needed to make up his mind. Long story short we decided to be just friends and that we should keep our plans to hang out this past monday. Just before I met up with him I mentally went through the do's and don'ts of being friends. Don't let him pay for you. If you do hug don't stand too close and make sure it doesn't last too long. In my mind these are all things that just naturally happen with guy friends. Well as soon as I saw him I forgot everything. We ate at this incredibly romantic Brazilian restraunt and I had a fantastic time until we went to say goodbye. He tried to kiss me and I turned my head. I have never done that before. But in that second I remembered that we are just friends and he doesn't want to date me. It felt like someone had just split my heart open. So I will be keeping my appointment with the stake president tomorrow to turn in my mission papers.
