I ran into my first HS boyfriend about a year ago in the Galleria, and I am happily married. We have had virtual contact before (MySpace/Facebook), and he said that he was supposed to be the one that I married. - but respectfully left it at that. It didn't work out because He was a male slut during our HS years, and I was very morally conservative so....I couldn't see a future with him.
Anyways I had not seen him in person for many years 14 years or so, and was extremely overwhelmed with emotions. I had no idea that I would feel that way. It was as if all of the feelings were still there from when we were dating. It was very difficult to keep my composure, but I knew that I had to remove myself from the situation. He offered to get me a picture of our us in "art group" that he kept in his car, I told him no thanks b/c I had to run. (He also told me that he keeps a large painted portrait of me in his gym/garage(we are visual artists)). So, obviously he has thought of me over the years. This man was my first kiss, boyfriend, and heartbreak - the guy that every girl wanted. Also, a professional fitness competitor (so, body is tight). Basically still looking good, but to see him a man now instead of the boy that I tried so hard to keep working things out with - was very overwhelming. We were always off and on well out of HS, but he was too busy taking advantage of his good looks. We would never officially break it off - I just would distance myself and lose contact.
So, OP I understand the flood of emotions, but this is a trap. He is divorced, but I am married.
I am a Christian, and while some ppl take their morality lightly - I don't. I almost felt compelled to kiss him - as if when we were still together. Like I just had those romantic feelings still there/ like we were never broken up ...it felt natural. So, I knew that it was not a good situation to be in. I hugged him, and left I teared up afterwards b/c I will always have a measure of feelings for him. However, I would never ruin my family for a "fling" or a whim of emotions. I have been through thick and thin with my Hubby, and I have two wonderful children that would be damaged. = not worth it.
If he is married, and considering options with you - what do you think he would do with you??? The same. If he becomes available for reasons that have nothing to do with you - that is different. Don't be "that" woman. It will cheapen you and any type of relationship that would come from it.
