I myself would like to know the answer to your question. I recently found out from my husband that he has been unhappy for awhile and no longer wants to work it out. He tells me this now after 11 years of marriage and 14 years of being together. I also for a period of time did not feel happy especially when he cheated on me previously. But I didn't want to give up, I wanted to succeed as a family and gave him a chance. Now after having our second child well she's a little over one he decides to be open about his unhappiness..ugh sucks because I want to let go just as easily as he is but I find it hard. In the long run I feel it has to end but what a twist and stab to my heart and soul. I guess the fact that he has found someone else at his job too should be enough reason for me to let go..but it's so hard.
