What's interesting is that some people clearly find it very difficult to find partners, so when they get one it's both a mixture of surprise combined with thinking that it won't happen again and/or they can't be bothered to return to the seeking/attainment process. I wonder how many people stay in relationships for that reason.
A large number I imagine. I also know of large numbers of people who got together in their teens and 20 years laters still argue like teenagers, they clearly aren't meant for each other but they stay together.
