What do we do if it's the women complaining that she wants the keep behaving like a teenager and the men is too responsible for her because he doesn't want to waste money and wants to take care of the kids? Should we throw her out?

It could a long road to reform her but could be worth the effort. I’d recommend introducing spanking for bad behavior and make it your responsibility to make sure the rules are followed.
Responsibility and Leadership - you aren’t going to change her by complaining about behavior. Make the expectations clear and hold her to them. She can comply or not but it is her choice. Lean away from her a bit.
