I don't want to get officially married because I disagree with the foundations of the instution and what it stands for. It may have evolved, but I still don't see why I'd want to enter into something that, for all practical purposes (well most), has no relevance. Having some priest/minister/public official pronounce marriage does nothing to validate people's love for one another. And I don't buy the whole 'it's nice to declare our love' argument. If you need to declare it to other people, then you tacitly admit that how they view you and your spouse is important. If you love someone, the world does not need to be made aware.
As for marriage defined as a permanent relationship, I'm not actively against it. That said, I think I'd grow bored of waking up beside the same face for twenty odd years. But that might change, so I leave myself open to the possibility.
