Love has its own pros and cons, if you are in a relationship, then it's not at all necessary that it will always run smoothly. If there is love then surely there is a fight and I seriously accept this fact. The time when you patch-up with your partner after a long fight is the best time in any relationship. And it holds back the love and bonding between the two people more strongly.
Down here are the points which you should follow to avoid fights for a healthy and fruitful relationship.
Whenever you start fighting, the very first step is to try to figure out the reason behind it and confront the mistakes whosoever has done it.
Avoid violent communication because non-violent communication helps a lot in resolving fights. Be precise to the point you want to explain and I'm sure your partner will understand your feeling.
You should be strong enough to take the responsibility of not fighting from the next time. Still if you and your partner fight, then you should be the first one to stop it.
Ego is the worst thing in any relation, so try to maintain a one hand distance from this word and sort out the misunderstandings by apologising from your partner.
Being happy rather than always proving yourself right is much more important. So, just stop showing that you are right and win the argument because it's not at all worth to win the fight in this way.
Sometimes, these arguments turn good as they teach a lot to one another. Give a chance to express views and understand one another.
If your fight turns into a terrible one, then it's better to set boundaries so that the mistake doesn't happen again. Wish you and your family a happy and prosperous new year.
