I don't think I saw your earlier post, but I'm sorry, anon. If it helps, I don't think it's a case of you not meaning anything to him at all, it's more likely a case of cowardice and him avoiding confrontation. A lot of people are like that - given the chance, they'd prefer to pretend a problem never existed rather than face it head on.

Now I don't know your circumstances, but surely you feel you deserve better than someone who'd rather let you suffer and wonder what went wrong after he agreed to talk about it. It's a cliche, but you're better off without him. Don't look to him for closure, look to people who love and care about you to support you in the aftermath and give yourself time to heal.
