So I have been fucking this girl for couple of months. She asks if she can come over tonight, I say sure, then she later texts saying "I am at a friend's house, so I may not be able to come tonight"

Now, "I am at a friend's house" is what she told me she uses to tell her parents when she is out late with me.

What is this? Is this a shit test? Is she out with another guy? Or possibly at a friends house..

I am choosing to not reply and get back to my work, and posting this question ... (pathetic.. I know)
