That's a nice thing to have. Although since marriage and especially child birth I usually need to fight for loneliness instead. Maybe I'll do it when I'm old, you know, alone.
you want friends that allow you to share and open up on problems that you face. as soon as you have your first fight you'll want some else to talk to.
a psychologist also told me that putting all your companionship needs on your partner can be burdensome. for example if i like to play board games and my wife doesn't then i better keep meeting others to play instead of giving up playing
