Hi Sosad55, sorry you find yourself here but as Job and Esame say this is a very good place for you to be to receive support.
Your H definitely seems to be on a high with OW, however as you know what goes up must come down. They won't be able to sustain such an expensive and time consuming lifestyle for long unless you failed to tell us that your H is a Hollywood superstar with pots of money! One day they will have to come back to the reality of ordinary life and a bunch of debt!
As Job and the others will say, you need to let him go. Not give up, but let him go on his own journey and in the meantime you should also go on your own journey to live your life as best you can without him for a while.
You don't say what happened at BD. Could you expand a little more?
