It is a normal part of even the happiest relationships. Though some fights can turn violent, it need not come to blows; emotional abuse can destroy your self-confidence and leave you feeling worthless, isolated and vulnerable to more abuse. Counsellors say it is often possible to spot trouble bulding up.
Body language is a key indicator. Finger pointing, arms folded across the body, fidgeting and restlessness are all signs of increased emotion.
Words are also important. Sarcasm and rude, abusive or foul language are a giveaway but you should also look for other clues. These include statements that make him look important and you look small, and angry ultimatums.
