I am going to tell H that I have been afraid to be honest w/him regarding my feelings for some time because H has been so angry at the world and has had such dramatic reactions.
That is totally fair. Of course he may have a fit.
I like your boundary about his watching D1.5 at his place too. Mostly b/c he's leaving a mess for you. It'll be hard esp. if he's doing the "I'll show you" stuff. He may make sure you run into OW. You've done so well, I have no doubt you'll handle it well.
