People are like puzzle pieces. You search and search for the right ones. You pick up a few that don't fit and frustratedly place them back in the pile. A few fall on the floor, and you seemingly lose them forever at that point. A few feel impossible to find.

But sometimes, a piece just fits. You don't have to rotate it around. You don't have to force it into the space. It just falls into place seamlessly. Sometimes, relationships are like that, too. Sometimes, you just fit, and it's incredibly clear that you are supposed to be that way.

Here are 26 signs you're an incredibly compatible couple, according to psychology:

1. Your personalities complement each other well

And you bring out the brightest, most comfortable versions of each other.

2. You appreciate and are genuinely interested in each other's passions
