Is it ok for your husband and father of your kids to go to a bachelor party?

My husband is 30, and I'm 23. We have a 2 year old, and 2 huge dogs. I have a gastrointestinal disease that keeps me pretty weak due to malnutrition, so I need help with stuff sometimes, but I don't whine. However, my husband works 6 days a week (by choice, he's on salary for 40 hour work weeks) and we rarely see him. Never been on vacation. Haven't been on dates since married. Is it silly I'm upset he will be gone for two days at a bachelor party?
