A lot of parents when they believe they are in a bad marriage wonder is it better to stay together for their kids or not. First of all we need to realize as parents who are married that marriage satisfaction goes down once we have kids and it goes up when they leave. There is a lot of things about marriage that when they don't work out that are bad mechanics. The foundation is good, the engine is good, its just that the mechanics are off and that's why if I'm asking that question as a parent, one of the things I really wish people would do is to seek out good marriage counseling. I think there is a lot of marriage counseling that isn't good but good marriage counseling is very mechanical. What are the mechanics of your weeks? How are you guys doing? Are you enjoying each others company? If not there is exercises to remind you about why you wanted to spend the rest of your life with this person, have children together. There's exercises to get you there, remind you. How are you arguing? Are you arguing effectively? Again there's exercises for that. What's your sex life like? Is it varied enough or is it like flossing teeth? Is it open lines of communication? what our sexual interests are with each other and doing exercises for that. I think i would never want to end a marriage without at least trying those mechanical things with a good skillful marriage counselor. Maybe if that doesn't work that's information
