Did i do anything wrong?

i think i screwed up or i screwed up. okayy my friend said my other friend lets just say kate was lying about the things this boy was saying because he showed her texts of his to her. example would be he asked me to prom but he actually didnt she did. but thats not a big deal its just that everything she said was a lie. we also had a little probably in the begging of last year but i couldnt find myself to forgive her. but i didnt hate her. i also heard that she thought me and my friend were all that & we arent even that funny. but that stuff doesnt really bother me but still i dont no if it leads to my way of thinking ill of her. i also went to middle school with her but i never really talked to her but rumors about her spreaded the whole school she got asaluted and did some things with step family memebers and all this nasty weird stuff. i even asked her and she never denied she even said it. i also heard after her prom thing was over that she got fingered in the middle of the dance floor and a lot of people seen. she was crazy am i right? well i went out w/ my friend and her mom & kinda w/hasty feelings called her crazy & i felt bad for her & that the stuff she did & say i dont agree w/ it. but after 3 weeks she changed she was more relax she doesnt talk about guys as much & less crazy. but i went over her house & i feel like i did a 2 face ***** stab in the back thing to her. i told her to her face a few days ago she was crazy but diff. now but i meant it she mustve thought i was joking. i dont no people feelings change. what should i do. im confused. thanks & bye.
