Hi There
I am very sorry for your broken heart and don't want to add to your situation but think I can contribute as I've been here before.
Now that he's laid out the ground rules and explained that he has nothing to offer you, the reason he is still corresponding with you is because he still would like to enjoy the benefits of fucking you with your acceptance of his terms.
If a person loves you, they will take a bullet for you. If a relationship or a marriage is what you want, that person would walk to the ends of the earth to make you happy. If they won't, they don't love you by the correct definition of the word.
I know this because I wasted the better part of my life on men like this and its because of men like this that I'm still whoring my ass at the age of 34. I had potential, I had looks I could have been the girl living in the suburbs with a husband and 2.5 kids but I wasted myself on the wrong men.
My suggestion is if he makes any moves again tell him that if he's going to treat you like a whore, he should pay you like one. (Honestly, even if he does offer to pay you. If you love him, the pain of being treated like that by the person you love would be too much to bear and damage your self esteem.)
There are other men out out there who would self destruct for the benefit of walking on your arm and that is the man you should hold out for.
PS: I am half German if that makes me seem more honest or my story more credible
