How often do you disagree or just get irritated/annoyed with each other?
Honestly, it depends on how much we see each other. We are pretty much opposite from every other couple in the world in the fact that the less we see of each other, the more bickering occurs. Normally, we find something to nitpick each other on about one a week. It's literally, "Seriously? I just picked up the kitchen. Please put your dishes in the dishwasher." or "Meg, really? Can you please get up 15 minutes earlier and get the dogs out and fed so that I don't have to do it when I get home?"
How often do you argue?
Kind of answered this above... but real arguments? Very rare. VERY rare. Most of the time, if it escalates to that level, he's done something that could have injured him.
How often do you have a fight, as in heated words, really angry with one another, blaming, etc.?
There's only ever been two instances where it got to this. They were fights. However, even in a heated fight we never call each other bad names or put displaced blame on the other person. NEVER. Never, never, never. If he flat out did something stupid (and trust me, it's happened) he will get called out on it. But we are very good about communicating and don't let things fester, which is where displaced blame comes from. Our arguments include only what we are "fighting" about, never about things that happened in the past or things that we've kept bottled up.
Do you have the same issues causing disagreements, or do you usually solve it and fight about something else next time? Did anything change the frequency if fighting, such as kids, living together, time, counseling?
Solve it and bicker about something else next time, for sure. Living together cut down on petty arguments. Maturity also helped. Kids are n/a. Time is important, but never leads to huge fights, just stupid picking. Haven't done counseling, but found that a young married couples group really helped us.
