I would say that the biggest change for me was "No longer being busy."
And it drove me mad!
I went from running a small personal business, and having a very demanding academic job, and taking two grad school classes, and a very, very busy social life, and constantly eating out to... Checking my email, updating my facebook status, going to Waitrose, and making dinner.
I also went from having a very high amount of disposable income to being entirely broke!
That was a big change. The biggest change in my entire life!
My hubby had never lived with anyone in his entire adult life. Not a roommate, or a girlfriend, or even a pet! Suddenly, he had a confused wife, and two completely insane kittens, to contend with.
It was a very stressful transition, for both of us, and the stress led to bickering.
But, it gets better, over time.
Mind you, we of course still bicker, because we are normal, but not as much as we did in the beginning! Not even close!
It WILL get better.
