Have you ever heard the phrase "Don't [defecate] where you eat"? It applies here. You need a good, intellectually-challenging career & the money that goes with it. You may or may not need the emotional high of having an affair. I'm not going to pass judgement on the latter--who am I to judge? But no matter what, keep the two separate.

I occasionally get e-mail from an old girlfriend, but I am reluctant to go beyond just being polite. A while ago she told me she found our old tickets to the Woodstock Festival, and would I want mine back--complete with original mud! I bought the tickets in advance (I think they were about $15.00 each), but the tickets were never collected as the place was totally crazy when we got there. I said no. How would I explain to my wife that this ticket "suddenly" appeared! Wife knows I was there but I never told her the details, and I would rather keep that in the past. BTW, wife is a lot younger than me.
