<human>: We have been friends for years, but in the last 6 months, have become extremely close and talk constantly. We live 5 hours apart, and I have purposefully tried to keep it as just a friendship due to this, but the last few months I have really started to develop strong feelings for this guy, and I think he feels the same way - the timing has just never been right.

Regardless of my feelings, I have purposefully put them on hold for another reason - he has a close family member who has been battling a serious illness, and while he pours all his effort into coping and supporting, I felt it would be selfish of me to try to initiate something, considering the effort that would be required for that. I also felt, that in time of need, I would be better off filling that 'supportive friend' role rather than complicating it.

But now, I'm not so sure. He's very reluctant to open up, and I'm really worried his family member's battle is not going very well. I'm not sleeping because I know he is struggling so much, and I would give everything to physically be there to support him (which work prevents) - but I'm worried that it would seem 'too much' considering we are friends, as well as the fact that I would be getting in the way with his family (whom I don't know very well, and are obviously all struggling).

I feel I can't tell him any of these things - it would be selfish when what he is going through is a thousand times harder; nor do I want to add to his stress or give him anything more to deal with. But at the same time I want him to know I am here.

I guess my question is, am I doing the right thing by holding off? Is there anything else I should do/say to help him out?
Any advice would be appreciated, this is really stressing me out!!

Could you distill the essence of the text into 1-3 sentences?
