Common conflicts
The most common things couples argue about are money, sex, work, children and housework - roughly in that order.
Most rows start because of differences of opinion, but with patience and basic communication skills you should be able to negotiate a compromise.
If you find the same old issues come up over and over again, or as soon as one issue's resolved another crops up, then there's more going on than meets the eye. Below are some common reasons.

Unresolved issues
Sometimes people find they're fighting battles that have far more to do with the past than the present. Feelings of rejection or betrayal in childhood can create hot buttons that partners press without realising.
For example, a partner who's parent left suddenly in childhood may find themselves overreacting to a hastily arranged business trip. Or a partner who was always forced to do gardening as a punishment when a child may become irrationally angry when asked to mow the lawn.
Sensitive subjects
If there are taboo subjects in your relationship that always cause a storm, you need to mention them more often. If you don't, they can become time bombs.
Taboo subjects can include things such as a forgotten birthday or a time when you felt your partner wasn't there for you. Often it's something that represents a serious breach of trust such as an affair or a breaking of confidence. Burying old relationship problems is OK, but you have to make sure they're dead first.

Fighting for your deeper needs
Couples often use topics such as money, sex or housework to fight for their deeper needs within a relationship.

For example, an argument over who should pay for what may really be about where the responsibility lies and who's got the power in this situation. Rows about housework are often about unfilled needs for respect and worth. And arguing about how often to have sex is nearly always about feeling loved and cared for and deeper needs for connection and affection.

Hidden pay-offs
For some couples arguing actually plays a beneficial role, as it may be the only time they get to share their feelings. It can also add excitement to a relationship or be a way of getting attention.

Arguing can be worth the pain because of the joy of making up. And when you make up you get to reaffirm your love for each other.
Just remember: beneath the surface of an argument often lurks a much deeper issue, desperate to be let out and looked at - and you'll keep on arguing until you do.
