When you love someone its easy to forgive, but ask yourself just how many times do you forgive, I believe its as long as you can live together , I mean there is no such thing as a perfect man or woman, we need to look in the mirror, In my marriage the hardship came when we both hit our mid 40 s , he thought he wanted something young (which would n;t want him 0 LOL and i thought just maybe I could do it alone, . We were both wrong , because of our love for each other and my prayers threw God and him getting closer to God , we have been together 26 yrs, , 1. never lose the memories hang them on the wall, 2. never stop saying I am sorry or thank you or I love you, Satan loves to play head games, 3. what is his is your and vise versa, actually it belongs to God , with Kids, your worried about them , without kids you have to learn each other again, find yourselves time o honey moon all over again , IT YOUR TIME TO COME ALIVE KIDS ARE GONE , What do you want to do ? Hope God keeps your marriages and don;t be afraid to speak to God
