I'm sorry your relationship has come to this. I don't know as there is much in the way of advice I can offer. From what you wrote, it sounds to me as though your relationship with this man may just be over. And as much as it may hurt, perhaps it's simply time to move on? You may want to simply close out of any websites the two of you share.

My personal opinion is that perhaps the thing you don't want to do is to chase this man. This may only drive him further away. The best thing to do, from my perspective, may be to simply wait & see what happens. If he comes back to you... great! But if he does not, there's probably nothing you can do to make it happen I'm afraid.

One thing you do need to consider is that this man clearly has his own issues. This is not all just about you. But if he is not ready & willing to work on his own issues, you can't save him from himself. Under those circumstances, it may be best if your relationship with him does not come back together... as much as that may hurt.
