Yes, re-read Vincenzo's post again and make yourself busy in mind and body so that you do not contact him EVER again. Staying away from him will allow you to heal so that you'll be motivated to find another man who won't be so afraid and closed off to allowing himself to become vulnerable. He was hurt in the past and he's still carrying around that baggage so he keeps walls up that don't allow you in fully. Don't you let him make you his human bandage who he turns to make himself feel better, don't do that anymore. You sound like a passionate and smart young lady and there are men out there that are healed from their past hurts and are open hearted which makes them good relationship material when adding compatibility and romantic connection.
It's like quiting a bad habit what you're going through right now. Like cigarettes you can't quit smoking if you keep having a drag off of one, so don't keep feeding your habit of having him in your life by letting him keep you hooked with little drags (meaningless email/texting) of himself.
Feel better soon.
