@123Marvellover I know exactly how you feel. It's really hurtful and hard, especially if you were accused of doing things wrong when you didn't, but eventually you'll move on and see that they obviously weren't a good friend for you if they couldn't see the friendship between was better than anything else (and in my case with my greatest friend who was absolutely amazing, I mean ANYTHING else, so it was stupid for her to ditch her only good relationship. She's changed so much that idek who she is anymore so I guess she has made her choice and now she has zero support that she needs, but this is beside the point.)
Or she may realise in time that what you guys had was not worth ditching so she may come back.
Only time will tell but you mustn't let it get too in the way of your life.
