I'm hesitant to introduce my girlfriend to my extended family

I'm (30M), mag 1year kami ng gf (28F) ko next month. We decided na mag live in nung nag 1 month kami and sa 10 months naming magkasama kahapon lang ako naging hesitant to continue our relationship.

So here's what happened, her friends decided to come over and spent overnight. Syempre di maiiwasan mag kwentuhan, one of her friends said na lumipat sila ng condo which is around litex daw and since traffic doon only option niya lang na naiisip to commute faster is by Angkas and same stuff. I told her na understandable naman na mas convenient mag Angkas dahil traffic talaga don. And her friends ask paano ko alam. I told her that one of my aunts lived there. Sabi ko pa "Dinala ko nga din si (gf ko) don last year. Pero saglit lang kami, and she doesn't like the hassle kahit na nag Grab kami papunta at pauwi kasi sobrang traffic." And my gf started ranting how traffic it was, and she's confused din na may condo doon kasi sa pinuntahan nga namin mostly apartment and "squatter" nga. So I told her na yung condo nasa bungad while yung pinuntahan namin is sa looban papuntang Montalban.

Her friends asked a lot about the area and my gf just keeps saying how weird the place and stuff when wala pang 10 minutes nung pumunta at nag stay kami doon kasi I just decided to just get my computer para ilipat sa bahay namin. And never niya na encounter aunt ko and the only room (sa apartment) na napasukan niya is the maid's room kung saan nakalagay yung computer ko.

I was a bit offended tbh. Cause my aunt who lives there was the one who took care of me since I was a kid, dahil both parents ko nasa abroad. And to give back to my aunt, my parents decided to buy a rights for her para gawing apartment so she could have a stable income.

Idc naman about my gf's background, like ok, you're from private school since elem to college, but so am I. But that never excused the both of us to question those people who live in "squatter" places that she keeps on being disgusted with.

So this week uuwi siya sa province nila and after a month babalik siya and originally our plan was umuwi sa extended family ko sa La Union and mag stay sa bahay doon kahit 2 days (which doesn't look that great kasi normal house siya ng province na literally kahoy and bubong ganon). I already informed her what it looked like outside and inside, I even searched for it sa Google Map para aware siya anong makikita niya. But now I'm hesitant to even go or na dalhin siya.

And I know it's bad but yesterday while she keeps on ranting with her friends, in the back of my mind I'm thinking na "How can you say those words, when in fact you can't afford the lifestyle you have right now if I'm not supporting you and your family."

And tbh, it even made me question if itutuloy ko pa ba yung relationship namin or not. I just don't like people na "matapobre" kasi you don't know kung anong pinagdaanan nila. And I was raised by my parents na kahit anong meron kami we shouldn't judge other people's life.

I just hate pretentious or grandiose people na akala mo big deal na sila cause they have something that other people don't have.
