It isn’t love or companionship that drives us to seek others. It’s the drive to share something profound with someone, but if you can satiate the drive with profound discovery alone- all the better for you. Two solid options exist: depend only on yourself, or diversify your dependence on others until the dynamics of human interaction are negligible; i.e: one person falls, another takes their place.
It’s been a long time since the last time that drive was not satisfied.
