Why do I still want this ex as a friend in my life, when he treated me so poorly?

I don't know if you were physically attacked or not, but I would still call it batter wife syndrome. That sweet man maybe so sweet, but not igniting your emotions. Yet you are no longer with your abusive ex you have residue left from that relationship. As well as you may a spirit that does not want you to succeed therefore that spirit is causing you feelings that may cause catastrophic behavior and lead you out of your sweet relationship. Therefore buyer be aware therefore don't buy into your thoughts about your ex.
