I Am Confused About My Feelings

I have loved my friend John most of my life over the 32 years I have known him. A few years ago we attempted to have a relationship but he ended it because he felt guilty about dating his friends ex wife...even though my ex husband and I had been divorced 11 years at that time. My ex husband got re-married earlier this year and I am wondering if the fact that happened if that would change anything. John and I have not been intimate in several years, but this past weekend we spent the night together and of course all of my strong feelings have come flooding back.
