Ex contacted me after 6 months

[Beware of Junk Psychology...]

Hey guys my Bpd ex contacted me after 6 months and 4 months no contact on my birthday. She said hope all is well and wished me a happy birthday. I messed up and tried calling her the next day and no response. She has disappeared again and I have not heard from her in over a month now , I also noticed she unblocked me on facebook as well sometime before or after the reach out . I was wondering what this means and if I'll hear from her again . I also noticed she is hiding her replacement on social media there has been no guy on any of her accounts for almost 8 months now or so which I find is weird cause I know she is with somebody or I believe she is . She also has not taken down any photos of our stuff and keeps posting places we been to every few weeks this has been going on for awhile now she will stop then start up the photos again . I'm not in the photos there just places we visited together. She left and discarded me after 4 years

We can drive ourselves nuts trying to rationalize these things. My ex didn't scrub her Facebook of me even into her new r/s with the guy she left me for then married and was for a time our kids' step-dad. I blocked her for a few years and then deactivated my original account.

The pain is fresh for you, but what do you feel that you're getting out of following what she does?
