You socialize separately
You have separate social circles. You also have common social circles, but you have some separate ones. When you’re both very social people, you’ll have conflicting invitations, all of the time. So you decide it’s easiest that you go your way and see your friends, and he go his way, and see his friends. However, that’s not what’s best for the two of you. You feel close by experiencing things together. Sometimes, it’s worth it to pick one friend group—one event—and go to that together.
