Start off by give each other spaces and try to calm down. After calming down, talk to each other, and keep in mind to respect each other while talking and reproaching one other. Break down your problems and try solving them one problem at a time. When reproaching one other, always remind each other of how important the other person is and how you can't live without the other person and how you love each other. NEVER EVER EVER let anyone, no matter how close they are to either one of you know what's going on between you. Always keep everything to yourselves, and that way no one will pick sides.
Never blame yourself or your spouse for the problems, just tell each other that it was misunderstanding between you 2 that caused the problem. You meant something and he misunderstand it, and he said something that you misunderstood as well.
When you guys are done reproaching and diagnosing the problems, apologize to each other and hug each other and tell each other that you love and complete each other and you can't live without each other.
Never sleep mad at each other, because it causes more problems and more pain. Always clear the issues and make things for each other, your kids (if you have any) and your home.
With time, you'll get to know each other and the problems will decrease, and your love for each other will increase, and you'll understand each other and know each other.
Good luck in your relationship and hope everything will work out great between you.
