I (14F) have been together with my gf for 3 months now since she asked me out and i said yes but back then it felt like we were going to work out.

But the more we talked to each other i felt like breaking up because nine out of ten times she texts me smth its about how shitty her family or friends are or how about her energy drink addiction is.

And i personally dealt a bit with addictions before so i tried to help her get out of it but she doesnt even wants to hear it on how its unhealty to drink 3x a day and says "oh but its just so good" I keep telling her on how ots bad for her and i gen want to help her with it but if she ignores like that i dont want to be with her.

Today she texted me and i felt annoyed at it because it was just her complaining about her mother and saying that she doesnt sleep enough so she drank a red bull again. Which would be okay for me if it wasnt a daily occurence

For the past two-three months she has been awesome and always texting with me and replying quickly and when i wanted to met up she'd make the effort and show up. But i dont even love her and it feels wrong to stay with her since im unhappy in this relationship but since shes mentally unstable im scared shell try and commit if i break up.

I desspratly need advice on this, because my friends say i should break up since we dont go to the same school so i wont have to see her often but her mental well being worries me.
