What an insight. You handled it beautifully! kudos to you. And being so compassionate and generous to him for your eldest son's sake, you are setting a wonderful example for your children.
You are on the right track, keep your eyes on your goal. You H is watching you like a hawk. Look your best (men are very visual), smile a lot and don't let him see your feather ruffled.
Good luck!
