He's a waste of your time and I'm wondering why you are even contemplating any of his BS texts. Its clear by your history with him that he has some sort of mental issue that you can't fix and he can't either because he's very clearly the type that won't go to therapy to help figure himself out.

You told him never to text you again and he can't even honor that very simple request. He doesn't value you and he doesn't respect you or your wishes. He will however take you back for the sex if you are with such low self-worth that you'd go and give it to him again.

Block and delete him and accept that he's the turd that he's shown you over and over again that he is. Surely you don't want what he puts you through as a lifestyle? Surely?
