I find that for the past year, I'm always angry at my husband. Whatever he does just irritates the hell out of me. What can I do to stop feeling this way? I used to be so in love with him.

Agreed with Hui Qun, great suggestions. I have a theory I call "irritation momentum" - once you are irritated with someone to some significant frequency and level, it just keep going that way so everything he or she does make it worse. The way to stop it is first to recognise that you might just be irritated out of habit and may not recognise him for all the good things he is. (Human psychology studies has evidence that we remember bad things a lot better than good things) Once you are self aware, you can choose to create good turning points - a wonderful date night for example, to help turn the momentum around. But first you must let go of your own bias and admit that you are probably getting irritated disproportionately out of habit. Hope that helps!
