Wow, I'm sorry she is doing that, TishaBuv. How immature! I had a very similar thing happen and I had to WORK with her in a VERY small business(!) Also in our 50s(!) Honestly, you'd think you wouldn't have to deal with that crap after high school.

You are right in ignoring it. You're WAY too mature and sensible to get dragged in. Sending good luck for your healthy relationships.
