That people often change throughout their lives, but not just because they got married. Many people get married with either the expectation that marriage will change their SO or that the person will stay the same forever. Neither are correct. People will change, but not always in the ways that you expect and you have to be willing to adapt to them. -Tazi752000

When my grandfather asked my grandmother to marry him her father made them both sit down and write a list of 10 deal breakers. They then had to discuss them all to decide if they could both live with them before he would give his blessing. In over 50 yrs of marriage, neither one crossed the deal breaker line and they had a head start on open communication channels from the experience. The other thing they did was to ensure that each of them got at least one hour of my time every day from Monday to Friday (the other would watch the kids and there would be no chores done during that time) and weekends were family time. -GrumpyKitten1
