Celticgirl, boundaries like you gave him are not to punish him---but, to detangle you. Giving him the cold, silent treatment won't accomplish anything, in my opinion.
I'm guessing that his "making nice" is so that you will return to the old status-quo. Maybe he is sorry, right now--but sorry isn't enough to make changes. It takes sustained action to make changes.
You might communicate to him that you no longer listen to words--you look for actions.
