I am sorry golden, whilst this isn't much consolation, at least he gets to mooch off someone else now.
Until they get fed up of him.
Just watch he doesn't come crawling back to you when it does happen.

Give yourself time, don't feel bad for grieving it's a necessary part of loss.
Your so much better than that whole situation, and so much better than him without a doubt.

I wish you all the best with moving forward.
Take care.
