Want to make my own money, but no support

I support everything he does but when iut comes to me, he doesn't want to help me at all, I don't get it. Supported and helped him with his business that's not moving yet and now he doesn't want to help me with mine, I just don't get it, it's what I love doing, but at the same time I just don't get it. Like wth am I doing?

*I pay for my own bills without his help, it's been like that since day 1 (been with him for 4 years) and we don't live together, only minor bill he wanted to pay was netflix, but I took that back over too

*has this whole thing now of not trusting me, if that's the case wth are you with me?...his mother and family told him to never trust women on account his ex-fiance cheated on him, so why be in a relationship period
