Now,now Cake. I know you wish he would just go away. But the reality is that you wish he wouldn't. I know he has sorta hurt you in a way. But for now all you can do is be the best person.
Just be kind if he ever comes up to you and ask for small personal questions like "how are things going". Just answer short and brief. And if he rubs your shoulders again, just tell him that he does not have to do that but in a kind matter.
This will help you forget him and perhaps have him ask you why the big change of heart. It will drive him nuts.
