1. Control your anger

Find a healthy way to release your anger. Take a kickboxing class or go for a run each morning.
If you get rid of your pent up energy early in the day, you’ll be less likely to fight later on.

2. Always be willing to make compromises with your partner.

Compromise is the name of the game. When you get into a relationship with someone, you lose all sense of complete independence. You have to understand that you are sharing huge parts of yourself with another person. You are choosing to open yourself up and to let someone else inside of your heart. You might not necessarily be okay with everything that your partner is bringing to the table, but you always have to be willing to make some compromises here and there. Be mature enough to talk things out and find a middle ground where both of you can be happy with the choices you make in the relationship.

3. Swallow your pride and always apologize whenever you realize that you’ve screwed up.

Be the better person. Take the high road. Always apologize whenever you find yourself making a mistake. Don’t be a brat about it. Apologies might make it seem like a blow to your character, but the truth is that your partner will always love you more for being able to swallow your pride. Being willing to make apologies is a sign that you have a developed sense of maturity. The best kinds of relationships thrive on mature couples who are able to put the needs of the relationship above their own.

4. Don’t bring up the past

This is a huge step that I need to learn. I would say, one of the key ways to stop fighting in a relationship is to stop bringing up the past.
The past is the past and the more that you bring it up, the worse the fight can actually be.
Bringing up the past can also bring up a lot of old emotions, which is never good.

5. Be more understanding of the times your partner treats you ‘badly’.

Not everything has to always be about you. If your partner is acting particularly cold towards you, it may not necessarily be because of you. Just because your partner isn’t acting all bubbly and endearing doesn’t necessarily mean he/she is mad at you. You have to take into consideration that your partner is also human and is prone to having bad days just like the rest of us. Instead of being all combative and confrontational when your partner is in a bad mood, try being more sensitive and empathetic. Approach your partner with love and kindness, and ask how you can be of help.

6. Don’t Say Something You Regret

If you’re furious with your partner, sometimes the best thing you can do is leave the room.
Return in an hour, after you’ve calmed down a bit, so you can have a rational discussion.
It’ll be more productive than simply screaming at him until he apologizes.

7. Respect the boundaries that you have set for one another.

Just because you are “sharing” your life with another person when you choose to get into a relationship doesn’t necessarily mean you have to give up your individuality entirely. You are still entitled to your boundaries and your desires for solitude every once in a while. You and your partner have to establish your boundaries early on in the relationship and you always have to respect them.

8. Always be sensitive and mindful of your words and actions.

Words and gestures can impact people in ways that we don’t always understand. That is why you must always be extra careful with the language that you use when you’re talking to your partner. You don’t want any unnecessary arguments to arise as a result of misunderstandings or tactless words.
