Why do some parents stay together when they are clearly not happy?

It's because they thing that it is the best they can do for their children in order to keeping the family united.This can be damaging actually because they cannot erase the unhapiness too therefore affecting their children

Some parents stay together when they are not clearly happy for the sake and future of their kids. If they get separated it might have great impact on the tender minds of the kids if the kids are small. The parents might be bothered about the future of kids keeping their ego aside which is really a good thing. If the parents get separated the kids not only get hurt mentally but have impact on their education, career and even on life and it might lead them to anxiety and depression.

Some put other priorities like commitment to marriage or joint parenting as a priority over their own happiness due to fear or background beliefs. Their childhood could have lead them to believe that the other priorities will be more honorable to fulfill than their own happiness. They may also not even know what happiness is, so they may be repeating patterns of relationships from their own childhood. These decisions are not easy and happiness is also uneasily defined. Children should know that although parents consider children in such cases a lot, the reasons may be much deeper than just for the children.

Unfortunately not all parents are the same - there is no magical fix to ensure that relationships work out, but usually when parents stay together it can be a number of things. Usually, it comes down to a sense of obligation, to ensure that the children they brought into this world are taken care of so in essence, they are 'doing it for the kids'. However, some times it can be a case of they haven't lost what's important, hope; everybody goes through rough waters at times, and they may be hoping they can sail out the other side and everything will be fine.

This is tough. For some people, it's money. Divorce is expensive, there are a lot of details that have to be figured out and it can be a very exhausting situation. Othertimes, it's because they still have hope that things will work out, even if it means suffering in the meantime. Most commonly though, it's for the sake of the children. They don't want to separate kids between households or potentially hurt their kids but they don't realize that kids are also effected by unhealthy, unhappy marriages and parental relationships. It's tough for sure. Good luck with everything :)
