@Inaventu- I understand where you're coming from on this. If I were still married, I'd have to think long and hard before reuniting with an old flame, even if it were completely platonic. I wouldn't mind catching up with some people from my past, but I'd still have to keep in mind that we've both grown up and have taken different roads.
I did try to rekindle one old flame after my wife passed away several years ago. We were in the same high school class, and our reunion was coming up in a year or so. I found out she was divorced, and I was a widower. Back in high school, we were inseparable, and I always thought we would end up getting married some day. Unfortunately, she met another man at her out-of-state college, and we decided it was best to break up.
At the reunion, we spent a long time catching up on things, but it was like talking to someone I barely knew. I thought reconnecting with an old flame would stir up the same strong feelings, but it really didn't. We had our time together years ago, and now it was truly over for both of us.
