Important - if a guy listens to your really personal problems?

If a guy listens to your problems in detail and tries to help - and I mean really personal stuff - and reminds you that you were going to ask him about something instead of just having fun and ignoring it... is that a big deal do you think? And what do you think is the difference between a good friend doing that and someone who likes/loves you (God willing) doing that? Like for instance his brother helps me out but I think my crush knows that some things I wouldn't discuss with any other guy. I kind of told him that.

I mean being willing to possibly see you cry and we're talking a really deep emotional subject here. And sit and freeze in the car and discuss.
