I am really struggling with my choosing to go on a vacation with her sisters for 10 days. I am currently laid off from my job and we are struggling to pay our bills. Here brother-in- law decided to buy all the sisters a 10 day trip to Hawaii for his wife (my wife's sister) 40th birthday.

I feel this was extreme and my wife should not have taken a week off of work (with pay). Left me with the entire family and goes and vacations when we are in this turbulent situation.
I expressed how I felt but she still left and said it is paid for. I feel that she should of stayed or the 40th birthday party should be as extreme to ask to leave for 10 days. Am I wrong to feel hurt, depressed, and think that she should not have gone?
