I once dated a girl for a while but we stopped dating because she was just too BPD for me to handle. The passion & sex were great, but the mood swings, lies, paranoia, etc. were just too much.

We remained friends though for a very long time. Went our separate ways but were always in touch. Eventually she got into drugs & dating real bad dudes, and I tried to get her to get a grip and stop the drugs & ruining her life. She ghosted me. Eventually she responded (or rather her boyfriend did) that she was in a psych ward for rehab. Our friendship resumed when she got out.

A year later she died. I met her family at the funeral, befriended them. One day I mentioned her psych ward stay. Her mom said she was never in a psych ward. She pulled up texts on her phone from the date range when she allegedly was in the ward.

The whole thing was a sham. She told me she was in the psych ward / rehab to get me off her back. The txt from her bf was just her.

I miss my friend dearly, but finding that out broke my heart.
