Now all I need to worry about is if she cares - the signals to me say she is checking me out but maybe I am reading too much into it.
No.
No, no, no, no, NO, NO, NO!!
This is NOT ABOUT HER. It's about YOU. If you're doing these things to get a reaction out of her "that she cares," then you are not yet differentiated and detached.
It's a powerful, simple (but NOT easy) concept, but DBing is primarily about making YOU a better YOU. In so doing, you will BECOME a potentially more attractive spouse.
