Have you ever seen someone you care about go down a bad path?

Ex-friend of mine dropped out of college, moved into a super expensive apartment with her cheating boyfriend, and works 80 hours a week to barely afford their lifestyle while her bf hangs at home all day. It got to the point where she does “favors” for her mentally ill neighbor to get handouts for rent. Her denial over the situation has led her to behave in shitty ways - and now she’s facing eviction, has no friends left, and is tens of thousands in debt.

Instead of taking accountability for her life choices she’d just lash out at others. So after being there for her for years I was forced to cut her off. In her mind I was entirely at fault for the relationship ending and that she was a perfect friend.

Anyone else see someone they used to love go down a bad path and turn unrecognizable?
