immaturing 

The process of becoming less responsible and capable over time.

Often a trait of a middle-aged person who has given up on taking care of themselves - either due to personal choice or unforeseen, unfortunate circumstances. Someone who is immaturing was more capable and responsible as a young adult than at their current older age. They often displace their burdens on people who care about them.
