Once a month is fine, once a week is not so good, and everyday means there's trouble ahead. I mean, a serious fight, when your voices get louder and your feel angry against the other person. If you watch people, you can tell the happy couples from the unhappy couples. Their body language can give you clues. Sit in a shopping centre, and play a game, ask yourself how many happy couples you can find, and how many unhappy couples you find.
Unhappy couples tend to walk apart, look away from each other and communicate in short sentences.
Happy couples will be holding hands, or walking close together, often walking in step with each other and communicating with an open face to each other. If you are constantly fighting with the other person, consider a marriage counselor. Or examine your lives to see where the stress is coming from, and try to decrease the stress. Hire a maid or tutor to help you cope. Try soothing the savage beast and getting on her good side.
