I'm on the fence with marriage.
On the one hand, it would be nice to always have someone to travel with/try new restaurants/cook for. To have someone to kill bugs/snakes/amphibians/rodents. To maybe split chores.
On the other hand, it's really freaking nice not having to put up with someone else's schedule. What they want to watch on TV. Where they want to vacation. What side of the bed they like. Etc.
I imagine the pros do outweigh the cons, but I'm pretty content with my life at the moment.
