I was with my ex for 3 years- it started when I was 20. It was very intense and we were great friends but I was very immature and had a fantasy of how I thought my life would turn out. I wasn't ready to settle down. He was incredibly in love with me and he was heartbroken when I broke up with him. Within a few months I tried getting back together but he wasn't interested. I tried a couple of more times but he had moved on within the year.
I went through a period of grief and met my husband. We're now happily married. However, every time I see my ex in a social setting I end up in tears thinking of the what if's. Why is this happening?
