A few months ago, me and my best friend got into a semi argument and me being upset finding out he was breaking up with me since I used to date him, I was being toxic and said "fine then leave" I regret that I did everyday and I cant stop crying about it. I was such an idiot. And i recently sent him a long apology letter and he said "I used to consider you as my bff, even close family but now I dont know anymore"I havent stopped crying. Whats some good advice? We weren't as close as we used to be. Nothings going to be the same.
