First off, I think that you are a sweet heart. I’m assuming that he is your friend. This happens a lot to me with my female friends; they tend to develop crushes on me. Often times, I am totally unaware of their crushes. Primarily because you are friends, he wont be thinking about you outside of that context. You have to let him know. Also, there are times when I do know, but because I care more about her as a friend rather than a romantic interest, I try to keep it friendly between us. If he talks to you a lot about other girls, that means that he wants and need you more as a friend. There really isn’t much you can do to change his mind. You said in your question that he “don’t want to respect…[your] love.” You need someone who respect your love, and that doesn’t seem to be him.
