For those reasons and others my partner and I haven’t married, but we file our taxes here in Canada (and are legally considered, in Ontario specifically) as a “common-law” couple. We wear rings and have decided on what works for us, between us.

It’s working quite well for us for now. We’ve been together longer than any of my old, married (and since divorced) friends have.
