I am another who does not think this is wrong. I still am in contact with many people from my past , some of whom I dated. My husband knows about it , and since our relationship is strong, we arent jealous or worried that someone will come along and split us up. IF his wife knows (which she must - since she met you and left her husband in your home), I would say she is secure in her marriage, is a trusting and caring woman, and sees no harm in his friendship with you. That being said, if the "tone" of his E-mails would happen to change as this October trip gets closer, or if he starts getting more "personal", I might rethink things. You certainly don't want to be the "have his cake and eat it too" woman. It doesnt sound like he is that type person from what you said, but I would strongly recommend keeping it a "friendship" (since you know he will never leave his wife etc etc etc).

I have however, seen quite a few of my friends, have a strong desire to see an old flame, to see if that " feeling was still there". Two in particular come to mind. One started with E-mails, then phone calls, then they met for dinner (each traveling about 100 miles to do so). She was crushed by about halftime of the meal, there were no "sparks" left, and she could not wait to SPEED back home to her hubby ! The other was just the opposite. Once they saw each other, they both knew they "were meant to be". Both left their spouses, moved away together, and are now the happy little couple. One worked out, one didn't, and both of my friends had spent over 30 years wondering "what if". IF you are really into this as a friendship , and nothing else, I think it is great ! If you still have unresolved feelings, or think that you would be happy to rekindle your relationship from so many years ago, you could be actually harming your progress in forming a new lasting relationship with someone new. I dunno, I guess from my own situation, I see nothing wrong with being in touch even daily, but if you find yourself going to the computer to see if he has written, get upset if he hasnt, etc etc, it might not be a healthy situation for YOU. I rambled, hope you can see where I am coming from - or going with all this......and good luck !
