You're going out with a guy, paying all his bills, supporting him in almost every way. He's not romantic. Now he says he's afraid to lose you. I think you're answering your own question about what to do. To put it mildly, somebody who is unemployed, not romantic, and lets his girlfriend support him is what we call: unsuccessful. Of course, he doesn't want to lose you. This is a toxic, dead-end relationship that you should get out of as soon as possible. Have confidence and believe that you deserve better than this. Ask yourself what in the world is keeping you in this relationship. There's no reason for you to be in this relationship. Move on as soon as possible and if this guy threatens you or says he's going to do something to himself or does anything that tries to control you in any way, get as far away as possible.
