I'm so sorry you're going through this right now. I think you need to let go of other people's problems and handle your own. The only one who needs to contact your soon-to-be-ex is your lawyer who needs to be hired to find those assets and split them in two so flush all his calls.

In time your need to have him in your life will diminish. It's going to hurt for a long time but you'll see it happen. Nothing wrong with you, it's normal to go through this.

You really need to see a therapist and you need to build a group of friends and family who'll support you through this terrible time.

Keep hope, I assure you the pain diminishes slowly but surely.
