<human>: Give me the gist of the text in a nutshell

This began as we were both regular posters on a sub about fitness and we started messaging each other (initiated by him). Things started very tame, mostly discussing fitness but things slowly progressed to talking more about ourselves and sharing things about our lives. It didn't take him long to reveal he is married (he has never tried to hide it). However, we continue messaging as I figure our conversations are harmless, though I do feel slightly uneasy about it. 

As we continue I find out more and more about him and that his marriage is very unhappy. He also implies that they rarely have sex. He asks more about my love life and I share things with him – but nothing too personal. I enjoyed talking with him, everything was very natural, he was funny and we had a lot of similar interests. 

It got to a point where we exchanged pictures – nothing sexual. After this the conversation began to get more suggestive, he made comments about my body. I mostly ignored them but never discouraged him. It was always in the back of my mind that I shouldn't be talking to a married man but I liked him and I guess I liked the attention. 

Yesterday we were talking and he said "maybe we could talk about this more over a drink?".  I felt at this point things had gone too far and I panicked and deleted my account. However, this morning I got a friend request and a message on Facebook saying "Hey, what happened to your account? Thought we could talk on here instead x.". 

I know I could just block him and end it all but I feel maybe I should face up to him. Also I do like him – I don't want really want to end it without an explanation and he knows my name, he could probably find me another way. I didn't exactly lead him on but I never discouraged him even though I knew he was married. 

I know it was a bad idea of me to talk to a married man so I don't need to be told that over again. I just need some advice on how to handle the situation.
