Told me to never contact her again and now she's suddenly seeing mutual friends

[Corgicuddler95]

So as I've mentioned this week my ex finally just told me she never wants to hear from me again and quite frankly I feel free and relieved at this point. Her poor way of breaking up left me confused and unable to fully heal but now I know clearly where I stand.

My concerns today are that seemingly out of the blue she has apparently started inviting friends over (I've told who I heard this from to not tell me this stuff again). Since she has spent the last few months secluded mostly just talking to friends she made on the Internet and I know she has made little attempt to contact these people before, I'm a little suspicious.

It could just be my own paranoia but I fear she maybe trying to wrangle these people close to try and turn them against me, especially as I know she has litteraly lied (or at least greatly exaggerated) about things I've said to a friend who trusts me enough to understand I wouldn't say those things. I hope these friends are the same but it's making me anxious. How common would this be for BPD behaviour?
