Some couples argue a lot, others hardly at all. Couples can argue more or less at different times. There is no 'normal' or 'healthy' amount of arguing.
Some people think that arguments can be a good way of 'clearing the air'. However, the more you argue, the more likely you are to hurt each other's feelings and ultimately damage your relationship.
A far better approach is to make sure you regularly factor in some 'us time' and make sure you talk about any issues or problems before they build up into an argument
While disagreements are natural, they should never turn nasty - threats, intimidation, emotional or physical abuse are all viewed in law as domestic abuse.
