Believe me, I have watched my exH sink lower and lower for the last two years since we have been apart. Continues to this day. No job, no home, nothing except being a victim and blaming everyone else for his circumstances. It hasn't gotten him anywhere besides in a deeper pit.
SOOO true. Remember that you are the one that has the option of taking the high road right now, and making your life the BEST it can be for you and your son. Your H is taking the low road and probably will for the foreseeable future. Don't let that drag you down! You're doing great, keep it up!!!
