I find it odd that you went on more than maybe two dates with this person? And you do chores for her despite how she treats you? It takes two to argue. Believe me I know -our son is 15 lol. It also takes two to be in a healthy adult relationship. Healthy adults who are cranky/irritable make choices around their partners so they don't subject them to their crankiness. Make it "their fault" so to speak. Yes it's not just about loving feelings because you also at times have to stop, pause, breathe and either not speak, walk away discreetly to get yourself together, or change your tone because even if you feel love your crankiness might win over in the moment and then you haven't acted very loving. She doesn't choose to do this in part because she knows you keep coming back for more and -bonus -you do her literal dirty work. It's also about humility in a healthful relationship. I bet she doesn't talk to her coworkers or her boss like that right?
