SD? Not sure what that is. You really like this person, maybe even feeling you could love him...what does it matter whether you are "in love"? Ideally, you want to take time to know a person, then decide if he fits into your life in some way, perhaps as a friend or casual dating person. The concept of "in love" is not really a very good one; it implies that strong feelings of attraction are an indication of something important, or that the stronger and more intense your feelings are, the stronger and better the relationship will be. Most strong attractions are not anything that good or important and most relationships do not last. Just decide to judge the totality of the situation and the person as you get to know him more, rather than probbing your own feelings to decide whether you are "in love."
