Can you tell me what's wrong with this man?

My x has several college degrees and never had any stability. He is constantly doing projects that never amount to anything but mooches off others. I just don't get it. I had him get mental evaluations, apply for disability, etc. The kids and I are speechless. We have not idea whats wrong. It won't help for you to make mean comments...I've heard that alot. I'm seeking meaningful psychological or spiritual insight. Thank you. If you can answer this, you are a genius.
