Was I wrong?

So I’m moving in with my friend and his gf, she wasn’t there when I first arrived but upon her coming back in she didn’t say anything to me and also refused to call me by my actual name. I spoke to my friend about this and apparently she was like that with everyone that has visited them including his sister. He kept making excuses saying she’s tired but she works 40 hours a week or less, doesn’t have kids, or anything else to do while I work just as much, I’m in school full time, and have pain disorders and a possible autoimmune disease that I have to deal with. My family is also in town so I’ve been spending time with them and didn’t get back until kind of late last night. They both helped me get the rest of things up the stairs but during the process she kept saying I was quiet and making other comments about me since I didn’t go hang out with the both of them. I was tired and had school work I needed to do and also tried to unpack some of my things. She said that I was being bitchy since I wouldn’t go hang out while she was there but I’m not going to go spend time with a person who is being rude and doesn’t want to be welcoming to me and others. Am I wrong for thinking that way? Also she isn’t someone I’d ever get along with anyways.
