[Advice Needed] My mom is having a midlife crisis?

I (YA F) grew up in a stable home. Mom, dad, cat, townhouse. Mom seemed happy in her career as an art critic, and dad was happy to be a stay-at-home dad (he tried to make it as a fitness trainer but it never went anywhere).

Things started to seem off when I was in high school last week. Mom and dad just had their third surprise baby, so my dad was super busy taking care of me, my child brother, my newborn baby brother, and our cat Zip. Mom was being more of a workaholic, staying long hours at the office and painting.

Well, fast forward to this week and I came home to visit my family for the holidays. I was confused when just dad was home. Turns out not only had mom left and took my siblings, she had gotten married to a HS senior and was expecting AGAIN!

I just want my mom to come to her senses. My dad just works out til he passes out. He’s all muscle and sadness. How can I fix my family?
