My wife has not been working since our marriage 7 years back. We are in our early 40's now. Whenever, I raise the topic of children, she packs her bag and threaten to leave. Anytime there's a fight, she just packs her bags and leaves the house to stay with her divorced father. Even when there's not a fight, she comes up with some excuse and goes to stay with her father for 2-3 months at a time, leaving me alone. During that time, she rarely calls or messages me. When she does stay with me, things are fine most days. All my family members are either dead or out of touch. I want to start my own family and I'm financially well-off. Should I get a divorce?

Update: Maybe I wasn't clear. She isn't cheating. But she still behaves like a teenager who runs to her daddy for every problem. Her parents had a rocky marriage. She has broken off an engagement before. All her friends are divorced. She doesn't like to interact with anyone from my side of the family. In some of our fights, we did discuss divorce. Since her father is rich and she stands to inherit everything, she doesn't want any money from me. It usually me who calls her back.
