A former close friend kept me (f) around as a backup plan while she waited for her ex to “stop dating other people” so they could get back together. It fucked me up bad when I learned about it since we were REALLY close otherwise, basically a LTR in all but name. It sent me into a downward spiral that took years to recover.

I cut her out of my life after she showed up unannounced at an address I never gave her to tell me they got engaged.
