I want to confront this friend but I rather walk away

I noticed when talking to this friend she has an attitude when being talk to , I’ll talk about something and she had this look like , eyes widen and her face is just wierd , iv had multiple friend groups but this one female is off. Then I asked her what cups she had in her home and she said a specific cup that I thought was in the freezer and she replies like if I had her too many questions , it was an annoyed tone she had behind the fact I didn’t know specifically where the cups were, even her boyfriend corrected her .. he told her how wasin supposed to know if she didn’t explain it correctly.. throughout the night her energy was a bit off .. and I could tell she made little jokes , and I couldn’t tell id it was sarcasm or insecurities.. I’m definitely going to say something about it and just continue on my life..there was some hostility..her boyfriend would laugh at my jokes and she would murmur okay and play it off so no one can see she’s being insecure.. i could tell me and her boyfriend had a lot on common so we would have conversations and she would just sit there
