Kind of a follow-up from a previous thread.

So I talked to my GF about why I was uncomfortable inviting her to a LDW event with a bunch of people. Namely I explained that the previous times we've hung out with my friends that it's not been fun for me (I explained that I constantly feel on edge because of how she tends to tell me that she's feeling left out...followed by usually saying "it's fine, I'll just leave you with your friends"). I also said that I always felt on edge whenever we went drinking (namely that she consistently bring up things that are bothering her in the relationship when I'm too drunk to really talk about it...which always leaves me feeling terrible). She listened and then just said she felt really hurt.

Things got better afterwards (we went to another friend's bbq and saw a movie). Still, she just says those comments really hurt but that's all. Furthermore, she keeps making little jabs at me whenever I invite her to hang with some friends. Namely, she'll say things like "you sure you want me to be along, I don't want a pity invite".

So I feel like I laid out exactly how I felt and that she responded with guilt-tripping. I'm not really sure how to interpret her response. Am I an ass-hole for telling her that she makes me uneasy around friends? (I was hoping we could just talk about it and not have her just get all pissed at me)

Note that she's my first relationship to last longer than 2 months so maybe this is me just not understanding how things are supposed to work...

TL;DR Shared my uneasiness about something with my GF and she thinks I'm judging her unfairly. Can we work through this?
