<human>: This is all made worse by the fact that her libido is already way higher than mine.

When we got together, she was already on my upper limit as far as weight goes. She's not fat, or even chubby (BMI of about 23), but I'm attracted pretty much exclusively to girls that I can throw over my shoulder and overhead press. Since we've begun dating, she's put on ~15 pounds, and, while she'd like to lose the weight (not for herself, only because she knows how I feel about weight), she has expressed that she won't change her diet. Even if she wanted to workout (she doesn't), you can't outrun a bad diet. I anticipate the gain to continue.

She knows that I find smoking cigarettes to be the most disgusting habit a person can have, yet she started smoking. She wasn't even a smoker before we started seeing each other.

She recently got a pixie cut and colored her hair violet. I fucking hate pixie cuts and colored hair. I had no idea that it would be this significant, but it's had a huge effect on how attractive I find her to be.

Obviously she is her own independent human that can make their own decisions and I do not own her. How do I convey that I am no longer attracted to her, mostly because of her decisions? I'd rather not break up with her, but if this is who she is, I can't be with her, and I need her to know that.

Can you give me a shortened version of the text?
<bot>: She's conventionally beautiful, but doesn't arouse me. I'd like to let her know that so I can see whether or not she'd work on herself. How can I do that?
