I know this isn't an excuse....but do you think these two things in the last 5 months have happened because he has been trying to forget about business / financial problems and these are distractions that give him a buzz?
My advice would be to protect yourself and your D as well as you can financially and emotionally from the destruction your H is causing. He sounds like he is going to crash big time fairly soon - his actions don't sound like those of a rational, happy man.
