It's not you. It's him. And he hasn't gotten the new tools to have a sucessful R, cause if he did, he would look at himself and fix this with you.
He says one thing and then he says another like trying on hats in a store.
Either he's in mlc or he's a narcissist, but either way, he is definitly not healthy or right in the head. That doesn't mean that he can't be charming or evoke love in another, it just means that he can't love. He may pretend for awhile with this new chica, but as soon as he's really got her, his true colors will shine through.
I'm so sorry for your struggle and your pain. You didn't deserve this.
