I agree with what others have said, it definitely sounds like she’s jealous of you. It doesn’t excuse her being so nasty but I do understand how hard it is when everyone else is used to that behaviour.
If you’ve only got 6 weeks left of living at his parents house then at least that’s not too much longer to put up with her. I’d avoid her as much as you can in this time and when you do see her, ignore her as much as you can.
I wouldn’t reply to the texts about Christmas presents - can’t believe how rude that is. If she brings it up I would make a point of laughing about it and saying “what? I thought that message was a joke!”
Its a horrible situation to be in though. Not too much longer and you’ll be in your own place and can stop seeing her much at all like your partners brother has!
