Is it wrong of me for doing this and thinking this way I just really want to know
Most Helpful Girl
It's not wrong or right, you're just careful. This new girl is not that other girl so I'd try not to compare them. Of course, when you've been burned it makes sense that you do but if you like/respect her I'd tell her up front what you want to do (fifty-fifty with meals) and why. So that she knows that it doesn't mean you don't want to treat her to something. She'll understand.
