If adjusting to living together is causing problems, living apart isn't really going to help. You can only try to make living with someone work by living with them.
Resentment is easy to harbour, especially when someone you love says and does things you figure they know would be hurtful to you (I'm speaking generally, not you as in "you"). The really great thing about love is that it covers a multitude of wrongs. It neutralises resentment and helps you move past the thoughtless word/deed.
And finally, some advice from my mother that she gave me (because she knew I needed to hear this). "In marriage, even when you're right, sometimes for the sake of peace, you have to be wrong. Learn to let go of your right to be right, don't insist on it every single time you are wronged, it will make you easier to live with!"
I hope you can both work together and resolve this, and move forward together.
