I got rid of him after he used me.

Don't be bitter, just move on or do what your heart is telling you. It's ok! He'll come around eventually to see what an ass hole he is, let him work it out, he will move on to the next one and he will use them as he did me. If you want to be involved ask yourself does he have the right combination of other factors and future potential to take care of biz?
Maybe he just needs time to get it together. Maybe he's a weak guy and just needs some more time in the fire to grow bigger balls. God know his dick is only 5' small lol. You can tell him you still love him though. Just don't be bitter about it. Nobody who is independent wants to ask a man for money, just like you wouldn't want to ask a man for it. Play nice with him and see what he does, or help him find training wheels, don't overspend more than you want to give him. Just do what is fair and let the rest take care of it; meanwhile you owe it to yourself to have fun. Once an asshole all an asshole.  You are 33years old and what do you have to show for it 4 boxes . LOL That is so sad.
