Am I too petty?

My boyfriend (M29) invited me (F28) to his birthday dinner with his family. He said his mom and sister will pay for him as a birthday treat but me and his brother and sister's bf will need to pay ourselves. Me and him will celebrate his birthday the next day separately too, and i will pay for the dinner and gift. To be honest, im a bit disappointed because I thought when he invited me to the family dinner i will not need to pay. Because if i invite him to my birthday's dinner with my parents, we will definitely not make him pay at all. His mom is working but not earning much so i dont think she can pay for the whole dinner. And the rest are just around the same age as mine. But still, am i too petty to feed disappointed?how should i feel in this case? My perspective is from an Asian country.

IMHO: Just go with the flow and blow it off, its no big deal after all its His birthday to honor and celebrate.

If your family can afford to pay for guests if honoring you for your birthday than your very, very fortunate.

btw: if taking him out to celebrate his birthday again just the two of you, which I think is very personal as well as romantic, then its on you.

Times are tough all over.
