From one 50 year old to another, relax my friend.
We have endured many storms in the sea of life.
I am sorry you have chosen an unavailable partner. ( I have walked your path)
I am not going to sugarcoat this, as I might have for one of my teenage daughters experiencing a break up/heartache,........... we are 50 years old for God sake, ........... he spat in your face, .........what else do you really need to know or hear? His actions are HIGHLY unacceptable, THE END.
He has ZERO respect for you!!!! or himself, sounds like a done deal to me.
