Here's my advice - take a deep breath. Detach completely from your ex. He's a bum. He's proven he's a bum. Nothing is going to change that. Money wise, you took a hit...but you can and will recover, one day at a time. This will be something you can laugh about with your next, better partner...a painful lesson you had to learn to get to that much better, happier and healthier place you will be in.

Don't stress. The absolute worst is over. He's out of your life as long as you don't contact him again.
