Sharing Our Innermost Thoughts

Lemme know that did i overreact or did I do the wrong thing.?? So my friend she was going on a trip with her boyfriend and came to for some clothes and I gave them to her even though they were not even used by me like they were new i hlgave them coz she’s my bestfriend and she’s back from the trip and she just came and randomly through my clothes on the floor I took them and washed and next day she went to office from my room and I made her breakfast and lunch while she sleeping and that Day even she came and left for her boyfriend house and I made her dinner and send her safely the day next day she just came and left that box unwashed and it was smelling bad so I texted her about that and told her I could was if it was only you but you and your boyfriend both eat it so i didn’t feel good about it then she started shouting at me and after 1 week she bought me a plastic box and wrote a letter saying goodbye and asking for the money she spent on our parlour…
What is the wrong thing I did to make her that crazy
I did everything for her for the past 1. And she’s being like that for that thing
