I am married with 2 children. Been married for 8 years.
When I was 18 I went on holiday and met a man, we had a brief fling (as you do although didn't actually go all the way). He lived about 3 hours from me but we kept in touch for a bit. He didn't want the sort of relationship where he had to drive to me every weekend but he did really want to see me again and I wanted to see him. I liked him a lot and the feeling was mutual.
I met DH a couple of months later and never actually met this man again, just a few letters and phone calls.
I have always regretted not seeing him again and even now I get butterflies when I think about him. I'm pretty sure that we would have made a great couple. I have found him on facebook (we are not friends on there) and I just can't get him out of my mind. He looks pretty much the same and I still fancy him. I still remember what it was like to kiss him etc and I get really down. He isn't married but has a DP. I was gutted when I found out.
What can I do? I feel bad for keeping thinking about him but it seems to be getting more and more and I feel like "what if....."
