This is rich... She is a self-absorbed manipulating control freak... She claims to include you in her outings? Didn't she tell you she didn't want to have to feel obligated to include you? And didn't she begrudgingly include you recently because she needed a DESIGNATED DRIVER? now that was HUMILIATING!!!
I would respond by saying, "let's talk about all of this when you get home. This discussion deserves a face-to-face and warrants more than texts and phone calls." And leave it at that...
