In my case, we found that getting married changed the way that we view our relationship. We had already been together for over 10 years, but getting married was a commitment to each other that we'll try our hardest to make things work. It adds another layer of stability which is important for planning kids, careers, finances, and so forth. We can make choices as though our relationship will still exist X years down the line -- this isn't necessarily true, of course, but in the medium-term it becomes a reasonable assumption. It also brought us closer. Mutually agreeing to be each other's life partners is a big step. I don't have to worry that my partner is going to choose their career over me or vice-versa. We've both decided to put our relationship first, which causes a subtle-but-important shift in your relationship.
