What they all said
and this
if you chase after him trying to wring an apology from him, he is going to say and do more hurtful crap that is going to hurt and upset you more than you are now.
you are better off not putting yourself into yet another situation for him to throw your love back in your face.
It's like he's already run over you, if you get up and get in his sights, he will just run over you again. If you stay out of his sights, you give yourself a chance to heal and get on a different path.
I guarantee that trying to get an apology out of him will only make you feel worse.
A forced apology means nothing anyway.
