I feel guilty....

So there is a girl,she is my bestfriend. And I like her, but she is toxic...and she got the toxicity from her boyfriend, that guy who swears a lot and keeps insulting her. And yes she kept swearing at me, insulting me and mocking me.i wanted to break this friendship, but somehow the sweet and nice moments always pull me back to bestfriends....I hate this but I just can't stop it. Who knows if she gets nicer? But I hope she stops this cause she is one that I overthink about. But the thing is about one time when we played a game... I don't remember it, it was like one year ago. I think we played tag and then I accidentally hit her butt when I tried to chase her very fast and I couldn't see so I just tried to touch her body to let her know I got her but suddenly I touched it wrong and she got very angry and then she ran away super fast and then told everybody about this... I was so ashamed... I'm super guilty I wanna just stop overthinking about this because it's been in my mind since forever.... I already apologised to her, but the scene keeps replaying in my mind over and over again.... I just wanna stop thinking about this rahhh. Anyways, thanks for reading this :]
