what should i tell her?

yall i have a long term gf and we’re currently in college. lagi ko siyang sinasabihan na magbigay sa parents niya ng part sweldo niya and she always makes sure na magbibigay talaga siya. so its been months and nagbibigay siya ng pera sa parents niya and for me hindi naman niya obligasyon yon pero ginagawa parin niya, sobrang nakakaproud oo pero im sad at the same time. so eto na, one time nasa kanila ako nung inabot niya yung pera sa parents niya and broo nalungkot ako kasi di ko manlang narinig yung word na thank you or even smiled at her and instead hinanapan pa siya ng utang niya from tuition niya last month. huhu i was like wth sobra sobra na yung inabot this month and para naman yon sa tuition niya last month bakit nafefeel kong gusto pa ng bukod na bayad para dun. I know all the efforts and sleepless nights na naexperience niya yet a little appreciation could’ve helped ease all that bullshits. nainis lang akk kasi nakita ko siyang nalungkot that time. mind you yung half ng tuition is bayad na niya last month and sobra sobra pa ang abot niya this month. nakakaasar lang. so tell me mali bang mafeel ko tong ganto for her? what shoulf i do to help her because honestly i have no idea and ayokong mag talk bad about her parents lmao.
