Human relationships are meh.

Ultimately, we're all just solitary travelers. We join and leave the journey alone. Ultimately we're alone. Human relationships can't fulfill you. The reason they're there is for us to help the fellow travellers when they're lost or there's some glitch in their journey.
And when they're sorted we continue on our own journey. Everyone's destination is the same.
Since I'm Christian, I believe it's to return to the maker.
That's it. We're alone. And the only real lasting relationship we have is with the Maker.
