Contact her as to When it Might be a good time down the line to Get what is Yours and give Back what is Hers.
If you don't feel it is best at this time to see one another, then make arrangements with her in leaving them with someone you both know or On a front porch when she is not home.
If you do decide you do want to see her for these possessions, then maybe it is a sign where it is time to talk about more than These... Prize possessions.
Good luck. xx
