Am I falling off?

So I think I’m falling off right now because I’m low key turning into an “I hate my girlfriend final boss”. I feel bad because I’m genuinely starting to hate her a little bit but I don’t want to break up with her because I don’t t want to lose the friendship I have with her best friend. I would end it with her and ask just to be friends but she wouldn’t and would start to hate me and I would probably lose my closest friend. I would also feel bad for doing that to them and putting them in the middle of our break up. What should I do guys? #winnerthatsnotwinning 💔
