BECAUSE YOU LOVE THEM TO BITS... And can’t imagine ever wanting to be without them. This is the only reason that is actually wise. The only reason we’ll keep. If you would marry them even if you couldn’t tell anyone else, ever; if you would marry them if you couldn’t wear a ring; if you had to get married in an empty room wearing a bin-bag, and you still would. Then that’s a great litmus test that you should.
