KC,
You are asking for help. Help in moving on?
It sounds like the best considering that 1) he is married, 2) that he wants to go separate ways and 3) that it is a long distance relationship.
Transitions like that are hard. There really is no way to ameliorate the pain. The best way is to make a clean break (no contact) and don’t look back.
Find comfort with friends. Continue to take care of yourself with exercise, meditation, and other self care tools.
