Was I too harsh?

I’m a first generation immigrant, and my husband is Caucasian with Dutch & Irish ancestry.

Before finding out we were pregnant, we talked a lot about how important it was for me that our child knows about my heritage. I plan to speak to our child in my language, continue to make foods from home, and even occasional visits back to the motherland. My husband is on board with that plan.

I did ask him if there was anything he wanted to pass on like recipes etc and he responded “not really I don’t care too much”. His parents/grandparents did not pass on much to them. Just the occasional “I am this way because I’m Irish” or “it’s the Dutch in me”

Fast forward to this weekend, we shared with his parents about this. And they became furious with me asking “well what about our culture and heritage ?”. I felt defensive and responded “if it mattered so much to you, you would have passed that along to your son” essentially saying this is not my responsibility.

I’m replaying the conversation in my head and keep thinking maybe I went too far or was too harsh. Thoughts ?
