Hi, I would like to say, I don't believe you are sinning. I think people can fall in love in so many different places, and circumstances. Things happen in mysterious ways. I know you feel bad, but I would know that deep down somewhere it was all meant to happen, and maybe it is unique. I actually had the same experience, except the wife was my bestfriends mother. Now my bestfriends mother is about 45, and the guy is 28. So you see how much a difference there is. I had an affair, and I thought he loved me. I thought it was unique between this guy, and me. In the end, I ended up alone, and he stayed with her. I don't regret it though, everything is an experience, and I do believe he loved me, and that we were soulmates, or something. Something was def. different between us. From the moment we really started talking, It all changed. So you know keep your head up, and wait it out until this fall. If it doesn't change how he says, and he keeps putting it off. You got to kick him to the boot, before you get in to deep. Good luck and Don't feel bad.. I'm sure you have a good heart, and your following it well.
