I'm with kewlkitti on this, your moods ARE all over the place. Part of the advice you get here is to detach. This has 2 main purposes. First, you back off and give your wife space so she can think and maybe even miss you. Second, it allows you time and space to calm down, make changes in yourself and get your moods under control.
I know you're hurting, but your wife is too. You can't help her right now in any way except to become a better man. Would you want to be involved with someone who's moods were all over the place, changing from moment to moment? Probably not.
Kevin, take care of yourself. If you aren't taking meds you might check with your doctor and give them a try. They worked for me.
Underdog has a good rule about waiting to say anything when you're emotional. I did learn that in my relationship. If I had a strong emotion good or bad, I waited 24 hours before saying anything to my wife. Usually, the need to tell her anything was gone by that time.
Hang in there and don't give up when you're so down.
