Proud of it?
No
Why do you still stalk him/her on FB?
Same reason anyone stalks their ex on FB- just to be nosy.
Did he tell you he was married from the start, or did you only find out later?
I knew he was married from the start
What was his cover story (i.e. what did he tell his wife he was doing when he was actually with you)?
He used to work shifts whereas she worked 9-5 so we'd meet up when he had an afternoon off. A couple of times, he told her he was out/away with work.
Did he tell you he would leave his wife for you, or did you always know it was just a bit of fun on the side?
He said he'd have loved to leave his wife but I was clear I didn't want any of that. It was just a bit of fun for me. I very much doubt he'd have ever actually left his wife for me even if I wanted that.
How much older was he?
He was 38, I was 19.
Were you a mature or immature 19 year-old?
I'd say I was actually quite mature. I had a job, I paid rent, I was saving for a house. I'd been in a relationship from 16-18 and I felt stifled. When that ended, I wanted to go out and have fun and this affair was part of that.
Would you say there was a power imbalance in the relationship?
Yes but I think it was in my favour.
