My son found out his wife of 9 yrs at the time had been unfaithful to him for about 2 yrs. My son is on the road alot and not home but on weekends most of the time. So things happened. They had some tough times and he wanted to leave her behind. He walked out the door and started to drive away. But he decided he wanted to fight for his familly and he was not letting her tear their family apart(4 kids) so he went back and they sat down and talked it out. They are still together 2 yrs later. Their marrage is stronger because he was able to forgive and needed to account for her needs as well. They still don't communicate as well as they could but they are working at it.
Things are going to happen to test your committment. whether that is outside forces or mistakes one of you make. Bad choices can cause alot of strife. But you have to make up your mind that your marriage is worth working on. You chose that person and with that comes committment and responsibility. Through all the bad and all the good you have to think of the other one's needs too not just your own.
I am so proud of my son for having the courage to forgive his wife and for repairing the damage to their family.
So one thing I try to do when I am so upset with my DH is to go and list all the things he does that are caring even tho I feel at the time he doesn't care about my feelings but he really does just not in the way I want.
My DH always checks to see if I want something before he eats the last of it. He is quick to make me lunch or make supper if I don't feel like it. He does go out of his way to make me feel better when I am upset but when we have an argument and he hurts my feelings then I have to sit down and say ok. But he is a good man!
