Ended up ticking most of the boxes. Which brings us back to why marry in the first place? Obviously, a lot depends on your special other. The more boxes he/she ticks, the more you might wish to marry him/her (and therefore the less likely you should be to ever consider divorce - all other things being equal, of course). But marriage is hardly essential for a wonderful life of bliss involving 2 people and potential offspring. You get tax benefits? Woo bloody hoo. Maybe if I yearned to have a child, I'd think a little differently, but the planet's already struggling to hold everyone so I think the right thing to do is not have children...
