Sorry that you are facing this. 50% of marriages end in divorce. Yet you are here fighting for yours. I commend you for this. Love is a decision. It is not based on feelings.
Your H is going through a stage where his financial status is taking its toll. So, he's seeking sexual promiscuity to boost his ego. IMO, he's hiding from reality.
The best thing that you can do is to remain strong, do the 180s and GAL. The board is another gift that you can give yourself.
