Always, always, always.
Drunks, scofflaws, DWIs, deadbeats, always some kind of scum. And they are always encouraging her to stop for "a beer". And I'll give you 3 guesses how that plays out.
As soon as she says "my friend" I see red. I really wish she would get fired from her job just to get her away from those losers.
I find myself praying that most of her "friends" get run over by a bus, or get cancer.
i have had the same experience, they seek and stick around friends that are not quite healthy themselves ... . i think is a combination of:
1. Healthy friends dont stick / cope with the up and downs, paing black and white the BPD do to them. they might stick around a bit, but after a while, they realize that this kind of friendship is not healthy and they depart
2. BPD's seek validation, they seek to feel better about themselves, therefore seek people who are worse than them (in their perception), this makes them feel better about themselves (the BPD's), this makes them feel superior. it would be hard for them to feel superior when sharing a friendship with emotionally balanced and self confident invidivuals.
my opinion only of course, from waht i have seen
