there are multiple ways to fix a broken friendship. The most important is that you should be the one to approach out before the other person.
Communication is the key to any relationship. Hence, one of the two has to reach out first in order to fix a fight. Respecting your friend’s need for space is also necessary.
Time tends to heal everything. Hence, you should give your friend some time so that he/she calms down and is ready to talk.
Talking about the problem honestly and openly is also very important. This will make sure that there are no grudges left between you and your friend.
Accepting apology as well as saying sorry is the most important step in order to fix a friendship. There is no point in stretching a fight. Therefore, an apology is the best way to end a fight.
