This is just awful to read. I feel that you made quite a wise decision to turn to a collective for help rather than allowing the heartless creature you describe to quite simply - and easily, on his part - take you down.
His behavior is disturbing and erratic. As
motherofearth alludes to, the first fact that needs to be communicated is that some one with his propensity for hatred and defilement of his human "property" can't be given the satisfaction of successfully conducting himself in this way in the world.
My condolences regarding the miscarriage you endured. Being male, and thus being incapable of bearing a child from my own body, I really can't represent to an appreciable extent how I imagine having a beautiful child-to-be succumb to death within my body. But this must be one of the most difficult things you have ever endured in your life. I am truly sorry for your loss,

As human beings, we are - forever will be, in fact - hard-wired to live by and thrive on the social connections we develop with others in our lives. Judging by this reality, it is absolutely no small wonder that you have become so consumed by your ex-boyfriend's cruel verbal abuse and apparent indifference to the death of your child. You are a courageous woman for allowing yourself to feel those emotions in reaction to the implications of what he said to you. At the same time, do not allow yourself to "go at it alone," as they say. You've taken that miraculous first step, and I sincerely find that inspiring given your circumstance. Please continue to be open with us...
Lastly, his words bear weight. They necessarily affect you deeply, given the nature of your relationship with him prior to (and unfortunately during) is infidelity. But they are words, and can be restorative. As herbvore pointed out, the language I myself see you using to describe this wretched distortion of a human being indicates clearly that he cannot be afforded the
privilege of being a part of your life. As unfortunate as it may be, it's likely his "new and improved" girlfriend may one day endure the suffrage you yourself have. But you cannot afford to give your courage and strength over to exposing that to her. It s not your place, and if you so choose, you can free yourself from the bondage of that obligation by doing what is right - focusing on
you, and learning to trust again.
Thank you, from the bottom of my heart, for trusting
us.

Be strong,
And be Well.
