@DanV: Thanks a bunch for telling me all that! it really helps a ton!! I also want to say I wasn't looking for a future with this guy, I had just thought of it as a friendship (since I lack friendships, he did seem nice at first but then i was confused at the same time since he was married and constantly wondered how his wife felt about a friendship like this), hence I felt uncomfortable when these things occurred.

Can you tell me how i can detect/signs a guy that wants to be just friends vs a guy that wants to get into my pants?

Also, If you dont mind me asking, I would like to know about the trip that you made to the woman in England, how does your wife feel comfortable and not worry that something won't happen between you two?

I only ask because I have jealousy issues of my own and would like to work on that. I had something similar with a bf who spent the weekend in the hotel room with a girl-friend of his, and I just couldn't take it. (also, he lied to me about that weekend.. possibly because he knew i wasn't comfortable with it but he also know I was going through a very rough time, like i was depressed etc and i asked him to be there with me the next weekend because he was all i had and needed him...anyway, i wont get into that right now- thats probably 3 more posts and its the past.)

@Bloom, thankyou for your response to Dragon, it clarifies things for me as well I do think the SA is a problem here as well.
Could you tell me what you mean by him playing on my vulnerabilities and what my vulnerability would be? Am I too naive??

@TheDragon: Thanks for your responses but I feel everyone here is helping me deal with the situation because first, i'd have to learn what's going on in the situation so I can detect it the next time it happens. We are working on cure and not temporary relief. Also, I feel that if this guy is married and he is trying to get into my pants as everyone else is hinting here, his actions talk bad about his morals, that's him doing this, not us judging him.

And morality goes hand in hand to how to handle the situation, don't you think? first step would be to judge the situation/person/thing, then move forward.
