sometimes arguments never get resolved...meaning... you still think you are right and he still thinks he is right. however no matter who is right or wrong......you should never go to bed angry. because if you do it will only create more animosity towards each other and the time spent not talking to each other you end up spending thinking negatively about the other person which makes matters worse.
point being...dont let your pride get in the way of a good relationship. Apologize even if you think you are right and he/she is wrong.
i totally agree with u
