Did you ever think you marry the wrong person?

Did you ever think you marry the wrong person? We not getting along. We always aruging about stupid things.We like different things these days. He hates NYC. He used to come to nyc when we were just dating. Now he doesnt come at all. We haven't been living together for over a couple years now. How does a marriage work. When you don't put any effort into it. Calling me a fat ass doesn't help.
