UPDATE: AITAH for wanting to break up with my girlfriend

From the previous posts comments, I’ve decided I will be breaking up with her. I’m still very stressed out and worried that I’ll be blamed in the end. Does anyone know what I can do to stop this from happening? We are both part of a large friend group and over half of them will likely take her side, should I do anything about this? Am I wrong in assuming this? Were the previous commenters lying to me and I’m actually in the wrong? Any advice is much appreciated.

Additional info: This is a throwaway probably but this won’t be final update I don’t know how to post updates really but this is the original post’s link https://www.reddit.com/r/AITAH/s/ltdc2Wenns
