Honey, you have had good advice. Continue to keep the bakery closed! He is trying to use you. As long as he is seeing the OW there should be no room for him in your life.
You ARE the prize. He may not know that. Hell, he may not ever realize it. But you have to know it. He is a cheater, the OW is a cheater.
Maintain NC. If he wants a real, honest relationship with you it is up to him to do the work. You deserve that.
