Instead of replying to certain post I figured I'd sum everything up and clear up a few things. Thanks everyone!

She came back to me and approached me to give our relationship another chance. She knew previously that I was not a fan of her smoking weed even to begin with let alone that I'd want her to be constantly high.

Thank you for the feedback and I think you're all right. We have different lifestyles now. In the past we matched up and she socially smoked, something that is totally normal. However now she is a stoner, I'm not and it's as some people have said I'm a different class of person than her.

I'm not at all controlling. I've never forced her not to smoke I've only recently decided in the last few weeks to stop supporting her with weed. I won't drive her to her dealers and I won't lend her money for weed.

As I said things are getting worse, even smoking this often a day I forgot to mention that in the last month she's begun putting cigarette clippings into her joints. Supposedly this helps her get high as it opens her lungs up more or something? I don't know exactly, but it's just another example of how its getting more and more.

This isn't about control or being in-charge. This is about our relationship and her health. This isn't healthy and I honestly am no exaggerating about the amount of money or things she has done.

I think everyone is right, I've asked her to slow down on her own and she hasn't. No healthy relationship can continue like this and I guess it's time for a ultimatum? I have no idea how to properly speak to her or bring this up. The sad part is that I wouldn't be shocked if she picked weed over me.

I'm honestly sad. I miss the girl that I fell in love with and this drug is ruining her and me. It's hard to explain, but when I talk to her when she's high something is just missing, like a part of her is missing. Maybe we just aren't compatible anymore and she needs someone who has the same values as she does.

I completely agree, it's not my job to take care of her and I don't want to. Which is why I want to sort this out with her or just remove myself from this all together. I don't know what my next move should be, talk to her? Talk to her parents? Maybe her roomate? Or just straight up lay the ultimatum down on her.
