Having fights and arguments in a relationship is normal. You will want him/her to understand your point and he/she will too want you to buy his/her point of view. This can escalate and bring an argument or a fight. This cycle will never have a conclusion.
Use these tricks to help you solve out;
1. Leave the place of argument
Help your mind refresh and think how the argument will negatively affect the love you shared. Spend some time alone and try to know the cause and the solutions you will employ to your arguments to awaken your first love in the relationship.
2. Bring up the past sweet memories you shared
Once you realize the situation is running out of hand, bring up the sweet memories you shared before and how the experience was. This will completely change the mood and the argument will be covered by the great time you enjoyed together.
3. Ask for forgiveness
To avoid getting messy about an argument, state out what you said or did was not intended to sound as it did. Apologize and show how you're truly sorry, caring and how indebted you are to what happened. This will swiftly clear the place and a calm atmosphere will set in. Assure your partner than the mistake won't be repeated again in future.
