Q: A couple of weeks ago my husband (whom I love dearly) and I attended my college reunion. While there, I ran into a former lover (also married), whom I hadn't seen in 25 years. I'd had only one or two drinks but it became clear that we were both still wildly sexually attracted to each other. We exchanged numbers. I've been sick and guilty about it ever since, because I didn't tell my husband and because I'm obsessed with seeing this man again - just to catch up. Can you help?
