Can someone help me find the perfect song?

I have been seeing this guy for a couple months now and I am falling for him hard, and he is interested in me and says the sweetest thing to me. However, he is in the process of a divorce with someone he has been with for along time. I am afraid to fall in love with him and either A) find out he goes back to his ex or B) I turn out to be a rebound. Im looking for a song that kinda is similar to my feelings in this situation. HELP!!
