From my personal experience, these are two different things that people can have either, both or none of. For instance a person can be emotionally candid with you and yet make it clear that he is not emotionally available.
Can be the guy is emotionally available, but not emotionally open.
Can be he is both. Unavailable and unwilling to open up.
And can be neither. Both open and willing to be availed.
From what you've mentioned, I think the man you're interested in is struggling with some past and/or internal conflict and has trouble opening up. I'd suggest giving him some space and see if he reaches out to you.
I hope this helps :)
