Search Results: stick with one person

I have been seeing this really beautiful and genuinely nice girl, somewhat, over the last few months.
She has issues with her family, and she smoked weed a lot and cigarettes to spite her mom. She made an honest effort to not smoke during or before we saw each other.
We didn't see each other for awhile, and she got into a relationship with a guy who cheated on her and got her into acid and cocaine, but she insists she isn't addicted, because she got hospitalized because of it.
She then transitioned to a relationship with a girl that went sideways within weeks. She moved back home, and she's tried to reduce weed, no cocaine, and more drinking.
I was the only person who would check in on her, and she said she truly likes me. She at one point said she wanted to get out of the drugs and cigarettes and she felt someone more positive like me would be able to help.

She party said that I'm good for her, and I make her happy. But I'm not sure.
She's kinda stuck in an arrogant mindset and I'm not sure she's gonna be able to get off the drugs or fully believe that I'd be a good thing for her.

At this point I don't know what to do. I really like her, but I'm not sure I can really change anything or be able to help or anything. I don't know what I'm trying to say.

I guess I'm asking whether I can do anything or if it's worth it and she's a lost cause..

The popular culture/internet relationship 'expertise' is full of advice on how to be independent, and that seems to be reflected in what people believe - that you must be fully independent before you can commit to anyone.

Being in a relationship seems the least popular - who needs the boredom of being continuously connected to one person when you can have all those choices of what to do with yourself (I disagree, just paraphrasing).

Then there is the in-between - you are sort of in a relationship, but you limit your availability - some people seem puzzled at the mere suggestion there is anything more than this (no telling your significant other where you are or what you are up to, no 'giving in' - with the obvious question being who will cheat first)

And then, of course, complete refusal to get involved with anyone because you are told you must be independent - and you stick to a certain loneliness in attempts to master this monk-craft that is being sold as a cure for all ails. Presumably, the benefit of independence is you are allowed all the flirts and flings and hookups - though I am yet to find someone who finds any of it fulfilling (anyone I've ever met with that as a goal was simply lonely)

Where are you on the spectrum?
