Yes, you are.

This food makes your children happy.

Your children's happiness is important. Do you not think your children deserve to be happy?

Do you think your children should be without something that makes them happy for your own preferences?

Are there things you like to eat that your wife does not like to eat but she makes them for you anyway?

You are not being excluded, your children are being included, and you are excluding yourself.

Also, your wife is doing all the work here, she is cooking. She gets to cook how she wants to, because she is doing the work.

Here's an easy solution. How about you cook dinner? That way you can have exactly what you want. If there are any meals your wife doesn't like, be sure to make an additional dish of Mac and Cheese.

Or, stop putting your minor preferences before your kid's. Why should your kids suffer because you are close minded? At the Barbecue, there were plenty of other dishes you could eat. There's always something I don't want to eat at barbecues. You could totally eat the steak, chicken, and veggies. If you don't want to eat the rice, just leave it there for others.

She's not being disrespectful, she's being a good mother. If you think your kids should go without just because of your preferences, then you are not a good Dad. I'm sure there's things you like to eat they don't.
