Why are you talking to her?
Ignore her 100% !
I had pretty much NO school friends ever. I find they will only stab you in the back when they get the chance & they are NOT worth my time.

I have NO friends, only buddies. I don't see them often, sometimes its weeks, months or years that I'll see them next. I chat ONLY online with some of my buddies & never to hardly ever see them.

I pretty much just hang out with Rob (hubby) & Tom (bro-in-law, he lives with us)
