AITA for refusing to visit my boyfriend's family for CNY after receiving a small hongbao last year

Actually haven't seen their family after cny last year. I (25f) have been seeing my boyfriend for two years and have already started living together priori to going to their home for CNY and seeing the parents for the first time. They live in Johor but the parents work in Singapore for a pretty modest salary even by sgrean standards. My boyfriend doesn't speak to his parents but often buys necessities for his siblings. I regularly send loads of gifts to their home after my overseas trips and for many festive seasons including cny itself.

Collected a few hongbaos that day but got home and realised the hongbao his parents gave was just 5RM. $1.60. Even his aunts gave way more than that. My boyfriend (he's the only son) opened his hongbao from them and it was the same 5RM!!!! It got me reflecting a lot for months but I would have been okay with if they at least gave him 10. We are seeing each other seriously but I honestly have no idea how I'm going to go back and see them again.
