I'm currently in a "friends with benefits" situation with a guy who is very much younger than me. This is the first time I've been in such a relationship, as I was married to my high school sweetheart before we ended our 10-year relationship. I have no experience in dating and when I first met this guy, I never thought it would be purely physical. We both enjoy each other's company, and I was crushed when I realized that it was a "friends with benefits" arrangement because I had grown really attached to him. I can tell him anything and it feels like I've found my soul mate again. It gets worse, too, as he is also seeing other girls — all with similar arrangements. I know the best thing for me would be to walk away, but I'm in too deep, and I know he enjoys my company when we're together. I also know he's not open to relationships, at least not with me. We don't see each other often because he's always busy, and despite all that, I still want to see him. What should I do?
