Not sure if I believe in "soulmates" but if I ever had one, it was to a married women. Lots of guys on here pointing fingers, but when you meet someone that the chemistry is off the charts and there is just a knowing of that person, it will hit you hard and it's hard to resist. She pursued me. I avoided it for the longest time just calling her a friend and not being sexual.
I didn't end up with her because I was not ready. My life was a mess at that time. I ended up telling her to stay married and forget about me. She was devastated and a year later left her husband and stayed single for a few years hoping I would come back. She was married and at the same time, as loyal as could be.
I feel badly for being involved, but she was leaving him anyhow. Still doesn't make it right,but that is the real world we live in. People marry the wrong person and meet the right person later. It happens.
