I dont know how serious issues are between you and your wife but when you both fight you simply go out of home and she is mature/adult can handle or tolerate this but believe me you dont even imaginethat how badly your kids are affected of such issues in home. coz they cant express there love to you both but when you both fight it actually hurts them and sometime when you both get angry they cant dare to discuss there problems with you both.. so plz think about your kids and plz dont make there small world hell just for sake of your happiness..
