I'm sorry you're having a tough day. It's more than OK to feel sad, but IMHO I don't think now is the right time to tell H you feel sad. You need to be acting 'as if' and while you're not happy with his choices, you are getting on with life.
You mentioned on my thread you read 'Eat, Pray, Love' (which I haven't finished). Do you have another book, or an old favorite, that you can grab to lose yourself in the story? Do something for yourself tonight like read, paint your toes or watch a movie, and I bet you'll feel better tmrw!
