My advice is to not sweat the little stuff. There is no sense in getting into a spat because he didn't replace the toilet paper roll or because you didn't put the cap back on the toothpaste. Make sure you are on the same page about things like money, paying bills, etc. I recommend that you keep separate checking and credit card accounts (DH and I had separate accounts for five years but then when we moved to a new city/state we had to switch banks and got a joint account. I'm still kicking myself about it, but now that everything is set up its a pain to change). Also, learn to live with the small stuff. For example, DH insists that all doors and windows are barred and locked at all times, even when we are at home (our neighborhood is safer then Disney Land) and refuses to sleep with the windows open. I think this is absurd but I live with it because at the end of the day it's not a big deal. I refuse to check pockets when I do laundry (if it is in the dirty clothes basket it is ready to wash) and I also refuse to pick up clothes off of the floor to wash. He learned both of these things the hard way by loosing an important paper in the wash and by having to go without underwear for a day because he found it very difficult to pick up his dirty underwear off of the bathroom floor, carry them into the bedroom, and throw them in the basket.
