For me, closure would be about knowing that my needs just weren't going to be met, there was an incapacity to do so.

Tough love, he did you wrong. Actions speak louder than words, hence the simple word 'sorry' falls flat. No contact might be the better solution. Your not getting what you want from him, hasn't happened and doesn't appear to be in the near future. He's absorbing your energy and emotions during a time that needs to be spent on recovering from the pain.

Of course, he must have qualities about him, that are loveable, they all do, it's that something isn't there inside him to comprehend where he needed to compromise with you.
