Should I just let it go?

I met a cancer male who I really like alot through a course I took. He is married, but has a long-distance relationship (I feel it will eventually end).
I haven't seen him in 2 months, but we have been in touch by phone and email. I have always initiated contact (thought just to be a friend), and he always suggests that we should meet, but never calls me back to agree on a time to meet. It has happened a couple of times that I set a specific time and he was not in the same city, so there was an excuse not to meet. Last contact he even suggested that I travel with him and some friends and that he would call me to tell me when they're going. He never called me back. I didn't either.
I understand that he is married and I have no plans to break his marriage, but I still want to have some contact, just in case it doesn't work out for them (a bit pathetic)
I really like him a lot (which doesn't happen very often), but I know I shouldn't have expectations either.
But sometimes I can't help wonder if we have a special connection, but what's stopping him is that he's married. Or it's all out of my imagination. I just can't seem to get him out of my mind and keep thinking 'what if'.
Would any if you ask him if he feels the connection or should I just let it go?

I just feel bad to think to confess how I feel cause then I'd be initiating something (even if I decide not to act).
I first contacted him cause he's organizes this course which I wanted to attend. He then asked to meet, so I assumed he's available, but I couldn't make it and then he traveled.
I then met him at the course (some months later) which was for 10 days (in same place), so that's the interaction I had with him. But then he said he was married and I didn't try to make any moves (but I felt the chemistry) and I really admire him.

He also doesn't have children.
I can't imagine his status will change for some time. I also spent only 10 days with him, with no romance and he's been some years with this woman.
I just feel a bit frustrated liking him. I also believe he will not continue with this woman, but you never know after how long; a year, two, three,
He has suggested a couple of times to meet and then I'd agree, and he would back up with no real excuse. I also haven't been pushing it either (to why he can't meet), cause I wouldn't want to be part of a break-up, so I'm trying to deal with him more as a friend. Only the last time he suggested that I travel with him and his friends, he flirted quite a bit on the phone (of course I responded), but then he never called me back and I never asked why.
I guess I should just take the advice of letting it go.

Thanks scorpqueen/
I also know how stubborn I can be (aqua), especially in matters of he heart. I hope to learn to be more easy on myself.

Wow another Cancer-Aqua couple.....can someone please give an insight on my discussion in Aqua forum..........thnks

actually tejas, it's not a cancer-aqua couple...it's an aqua that wants a cancer who is already married...that's quite a bit different....

I kinda disagree as cancerian man......i think you should go for the guy if you think that his marriage is going no where and tht he would be more happy with you than his wife.......As i cancerian i can say tht he doesnt want to leave his wife bcoz at the moment he doesnt have anyone as such to cling onto......and from your above replies i can imagine there must be a chemistry between you two.....give it a try and he might cling onto you,you have nothing much to lose but much more to gain........

really tejas?.... and you can't see the wake of destruction that path will leave?... What about his trust in her? What if she has a friend later on and says "oh don't worry - he's married" do you think he will trusty her knowing that HE was married when she went after him? Even if there is no male friend involved do you really believe he will trust her? And what if their relationsup DOESN'T work out? She has given him a built in excuse to blame EVERYTHING on her "you ruined my marriage...blah blah blah" And the wife? Have you considered what it will do to her instead of knowing that the marriage ended because it wasn't working out, believing that it ended because of this woman? Can you imagine the hate and anger tyhat woman will carry for years if not the rest of her life? And what about the OP? I should hope SHE would feel guilty about what she did....regardless of whether his marriage would or wouldn't have lasted - she can't KNOW that it won't, she only believes it won't, and her beliefs could be completely contrived because she wants this man - she could even be inflating or even imaging thew chemistry between them because of her own desires.

I agree with you......but im of the opinion that aqua shouldnt cut-off just bcoz he's married and they could still be friends for the time being.....we can't make everyone happy or think what is right/wrong always from others point of view......if we do that thn we will always be on the side who's making all sacrifices and suffer......and if the things wont workout in future or the guy will blame the girl is being too negative in predicting the future or chauvinistic.....we gotta think and live in present more than in future.....No Offense Intended

but "stay friends" is not what you said - you told her to go for it.

one thing for sure..be it a sign or not..men are still men.. be it married one.
You play with fire and you'll get burn.
