It is pathetic to discover that a man that you've been so devoted and dedicated to for the better part of your years had been cheating! It is absurd! But do we do! Please for the sake of your health and your children try to forgive him to avoid having stroke and ultimately heart attack. It is very hard I know, but please you deserve to enjoy the latter part of your life, do not allow this to cause you eternal pain, get more interested in your grand children, use them to fill up your loneliness and before you know it you will heal.
