OP, you're not in a relationship with this man. Seriously, take a step back. His problems aren't your problem.
It sounds like you're hoping something will happen, but again, if he felt that way about you, then you'd know about it.
No doubt he enjoys the attention and someone to pander to his feelings when he's bored / feeling down, but he doesn't want a relationship with you.
Seriously, wake up and spend your time looking for someone who will love you as much as you love them.
I think you know this, and you do too, but I can't see it happening anytime soon, given how you've ignored pretty much all the advice given on here.
I know it's not easy as I've been in a similar situation myself years ago, and when I look back I get so angry that I was such as idiot and wasted X years of my life hanging about for something that was never going to happen.
