Guidance and a shoulder would have been a lot easier, Suzy! What broke me was sharing my home but not guidance or more directional help. I agree with you: we can't fix other people. It's nearly impossible to fix ourselves!
Here's the thing, in my situation: my friend would also agree that she was responsible for her happiness. She wasn't looking to me to provide it. All she needed from me was a safe and secure place, which I could provide. But what she chose as happiness was usually ill-chosen, and I saw that plainly. I omitted 95% of those details from my story, since the point wasn't to bash her but to examine myself.
Thanks for reading and responding!
