I need male opinion, but woman can help as well?

[serenity23]

I like this guy and he was going through very hard times, and got to a point that he could not handle it, and started crying, and I pretty much listened, did not do anything but really listen and try to relate to the situation he is going through. I know man don't cry in front of everyone, and neither I want to take advantage of the situation he is going through, ( although I do hope he was able to feel confortable and see the weaker side of him because he likes me) but I want for him to know he can count on me when he needs me and if there is ever an opportunity let it come on its own.

questions are:

1. How can I be supportive in the best way without getting my feelings involved.
2. How can I differenciate if he likes me as a woman or as a friend only?
3. Best advice I can give to a man?

He is not on any bad problems, he is far away from his family and will be able to see them until the middle of next year and works full time and there is lots of preassure at work
Thanks
