Am I doing something wrong?

So two weeks ago I put my two weeks in and a week later they ask me to stay a few weeks after my two weeks if a co worker was positive of covid. Well turns out her daughter has it and her boyfriend doesn’t want to watch the kid so he can go to work. So she’s been in the same household with her kid and she tested negative. So I assumed that there was no need for me to stay past my two weeks. So I when I was asked my the manager who runs his mouth. I told him this Friday was my last day. I get a text from my boss and he’s basically guilt tripping me into staying past two weeks saying she has to be away from her kid for another week and wait to get tested another week and I told him I was only staying if she was positive. So now they’re like “Welll i’ll just take you off the schedule and have someone else help me out” I genuinely think because I hate this job with a passion giving the two weeks was nice of me and now they’re like pissed off because I won’t stay unless she tests positive. I don’t think it’s my fault her life is fucked up and her child’s dad won’t help out. But trying to guilt trip me into staying a few weeks after my two weeks Imo is ridiculous. Especially if she hasn’t tested positive.
