AITA for not carpooling my coworker anymore

AITA for not wanting to carpool anymore?

About 7 months ago, I started working at a company where I met a teammate who lives on the same road I take to work (takes me 45mins without traffic). We started carpooling, where I would be at her house at nearly 7 am. However, she usually would still be asleep by the time I get to her house. so, because I did not like being late to work, I started calling her 15 minutes earlier so she would get ready. However, she would still get late. Mind you she paid me an agreed amount the beginning of each month.

That did not bother me until she started going to work on some days with this other coworker whom she liked “for fun” although he clearly had feelings for her. She would not always tell me when she’ll be coming with me and I had to call her every morning, which I did jot like doing. moreover, she would not be ready on my days, but i catch her ready early whenever she has to go with him (he gets to work at 9am while I do at 8am) which I really did not like. and it started really bothering me…

To add more spice to the story, the dude had an accident and wanted to fix his car, so she would need a ride. she did not tell me that, she masked it with a little hint of “i missed you, i think i will be coming with you now on” which upset me the most.

Now after that happened I decided to stop the carpool thing, and I told her I don’t want that to ruin our friendship, and she said “what you did is really shitty and I don’t want to be friends with you anymore” to which I replied “yeah okay whatever u want”

Now, I don’t know how the whole situation would be from her point of view, but i can’t see in what way she’d make me out to be a bad friend… because that’s what she told our teammates at work

Could you please give me some insight? it is bothering me because I feel like im the one wronged here
