So proud of you for getting out of this manipulative situation. Someone who truly loves you will give you the encouragement and the space to be your best self, not manipulate you so satisfy their own needs.

Be happy, enjoy your newfound freedom. He is not your problem anymore.

Good that you wrote to his friend, that may be the reality check he needs, might also help diffuse the situation.

I went through a similar breakup, years and years ago. The calls stopped after I met with a mutual friend and had a chance to tell my side of the story.
