Personally I think the whole concept of marriages is obsolete these days anyway. I mean, think about it. Just what is marriage there for?
1. An alliance between families to pool resources so that they don't starve. More hands on the farm and all that. Yea, that isn't happening any more. And it isn't needed either.
2. An alliance between individuals that ensures you always, absolutely always have someone to back you up. Again, not happening any more now that divorces are a thing.
3. A contract between you two and god that lets you have sex without being condemned by society due to stupid religious reasons. I'd hope we have grown beyond that.
4. A way of making sure your wife only carries your children and nobody elses. DNA tests are a thing these days so again no.
etc.
Maybe it's time we just let the whole institution drop.
