One of the hardest thing for husband

One of the hardest thing in marriage is hurting spouse's feeling.
Either you are on the right or wrong side,  either you have a good solid point or not,  either you are yelling out of caring or anger..either way,  we have all lost on our relationships.
Guys should always be gentle to ladies,  husband should always love and protect our wives but unforunately we are all just human. Seeing our wives cry or being hurt deeply inside are one of the hardest thing we have to face. Our heart gets soften everytime it happens and we can't help but to apologize since we, afterall, love our wives and cherish the relationship.
