Is it worth confronting my bitchy roommate if I'm moving in a few weeks?

I’ve lived with this girl for 5 months and will be moving out at the end of the month. For reasons I’m not entirely sure of, she’s always been kind of weird to me and most of our interactions have had a tinge of awkward to them.

For a while we were getting along and she was friendlier to me and then this other girl moved in and things got weirder between us. The other girl has some bad habits (not cleaning up after her cat, lights on, left a stove on once.) My roommate started mass texting us bitching about stuff this other roommate did when I wasn’t even responsible for it. I’ve also had some issues with her invading my privacy by going in my room without permission to give me my mail but I’ve never mentioned it. I try to be nice to her (I think I succeed) but honestly, I just don’t like her… For example, I’ll say hello and she’ll just screw up her face and give a really strained “oh hi” and look away.

We both work a lot and don’t see each other much so luckily contact is limited but tonight she really got to me again. I was standing in the kitchen washing my produce for the week and some dishes and she comes creeping out of her room with her typical rodent-like demeanor and says verbatim “Umm, are you done with the water? It’s been running LIKE forever!” (Emphasis hers)

This is becoming the typical way for her to speak to me and I’m really considering just asking her not to speak to me for the next couple of weeks if she’s just going to rude and passive aggressive. But I feel it’s not worth it? Probably not…
