What about marriage has surprised you?

To me, it's surprising how generally okay I am with sharing a life, a space and my heart with someone. I've always been on my own, living by my rules, working, travelling and pretty much doing a lot of things independently. I always thought marriage, living with someone would be difficult but it's been pretty easy to open up my life and heart. We have arguments here and there but it feels weird thinking about how life was before he came along. Guess that's how you know he's the one :)
