Before you get married, you should have a long, hard discussion about where you would and wouldn't be able to live. Some people think they love their partner so much that they could live anywhere as long as they followed them there. That's all well and good until your partner wants to live in rural Siberia for five years to do missionary work, and you start to realize that love alone isn't enough to sustain a life somewhere you hate.
A lot of people are willing to move somewhere for a job opportunity within reason. They would move from Illinois to Texas because they received a job offer they couldn't pass up. Others know they want to stay in one place for the rest of their lives, so they only date people who share the same goal. If you're a big-city boy and always have been and always will be, you are fundamentally incompatible with someone who grew up in a rural area and is uncomfortable living anywhere else. The only place where two people so fundamentally opposed could find each other is at University, and often university kids are unwilling or unable to determine whether their incompatibility is so bad that they need to break up. I know two people who met in college and dated for nearly a decade, even though they knew one wanted kids and the other didn't. Talk about fundamental incompatibility!
Once people get older, they're less willing to uproot their lives for a romantic partner. If someone has been alone for most of their life, they're not going to want to leave their friends, family, and community because of a romance that may or may not last. The woman in this story has been in an on-again, off-again relationship with her husband for years, and she's not willing to uproot her life and business to move to Texas with him. He's having a hard time taking no for an answer, despite how many times she's told him no.
