Divorce lawyer and married man here. Something I saw come up in divorces and tried to make sure was not happening in my own relationship is when one person feels they don't have a life outside their marriage and kids. That feeling will swelter and grate for years and I have seen it finally be the end of long marriages. The spouse who feels they have nothing outside of the marriage eventually blaming the other spouse. My wife works part time and is home part time, so I started being pushy about her getting out while I stayed home with the kids. (And I really did have to get pushy about it). She wound up playing on an indoor soccer team and getting drinks more regularly with friends. She would often thank me later for being insistent about her getting out and I think it helped relieve something that could have otherwise festered between us.
