OK, why is it a screw up exactly? I get that maybe you neednt have said it three different times. And maybe it was a knee-jerk reaction to her discussing softball and probably not the time to say it. But it is how you feel, right?
And if you didnt want her to come over, then you shouldnt have her come over.
I think she wanted to come because that is what the aliens do. You pull back, they get off balanced and move in a little.
But now you have said it, and she has heard it. No need to say it again, ya know?
I see no need for you to call her later. Let her sit with the info.
