Am I a bad person for not going?

So my mom and sisters are mad at me because I can't go to Hawaii this Dec. Me and my husband are struggling.. we have two little girls and they are both are my priority... I'm trying to get a new car and we are also trying to move into another home. I just started a new job... so I'm trying to save as much as I can. My mother is angry at me and she said I'm not living my life. She can be very controlling.. I'm a 33 years old woman with two kids. I want to have fun but I can't afford Hawaii right now.
