Concentrate on your partner's behaviour rather than criticising his or her personality
How to argue effectively
Arguing is a skill and skills can be taught and, with a little practice, perfected.
-Tackle on subject at a time.
-Bring up issues as soon as possible rather than save up for a deluge.
-Really listen to your partner's case and imagine, if for only five minutes, that he or she is right. After all, this is someone that you love and must, therefore,have some valid points.
-Aim for a compromise.
Concentrate on your partner's behaviour: 'Please don't leave wet towels on the bed' rather than criticising his or her personality. For example, 'You're slovenly.'
