I did get a text saying he apologizes for what happened. he said his intention wasn't to deceive but that he sees how i feel he did. he says i'm important to him and that if i need anything at all that i could let him know. otherwise, he said he'd let me be. he ended his text with 'cheers'.
The sad thing for me is I think he doesn't think he's in the wrong. He stresses on things like how in The Ethical Slut poly people are encouraged to continually change their own rules. So maybe in his head he's changed his rules and therefore he's right to do as he pleases. I doubt he's sorry at all.
