Am I wrong to be upset/angry about this?

My husband has been trying to get me to arrange for us to go out of town for a weekend since September. I finally worked everything out so that we would have the weekend after Thanksgiving, which is perfect b/c he has Friday off so it gives us a long weekend to boot.

Apparently his brother turning 30 trumps this. As of today, I have found out that we are going to dinner Friday night and then he is planning an out of town fishing trip for Saturday and Sunday.

Let me also mention that his brother is the type who floats in and out of our lives at his whim.

My husband said my attitude about this isn’t helping anything – just annoying him and pissing him off. I am angry and I am hurt.
