I'm a leo female and he's a taurus. I need advice!

What kind of advice do you need? You already know he doesn't want to be with you exclusively and you know per him that he's dating other women whilst dating you so I guess you just have to decide if you want to be with a guy that isn't going to be exclusive with you.

Suggestion....It really is okay to be with him and not be exclusive, you do have the OPTION to date him and date other men as well, if you can't have him all to yourself then he shouldn't have you all to himself and you both WIN.

If that's not an option, if being his girlfriend whilst he date others is not an option then don't go back, don't even be his friend, he lose because he chooses to lose and he'll have to live with that consequence.
