I've been legally separated for years, but not divorced. I have a 10 year-old son and one weekend we were going to the beach and a female acquaintance called and asked what I was doing and I said "I have John, we're going to the beach". She said "Oh, that sounds like fun, I want to go", so I picked her up and we had a great time. Not wanting to keep anything from my ex, I told her what happened when I brought John back home, and she had a major problem with it. Was I wrong, and should I put my social life on hold when I have my son?
