It has been 7 years since I

It has been 7 years since I discovered my husbands affair,after 21years of marriage. The pain has lessened and I have tried to forgive,but to no avail. Yes I do believe that it is possible that someone cannot ever get over the betrayal, the deceit and the physical affair of a spouse. I met my husband when I was fourteen and we dated for seven years before we were married. At the time of my marriage I truly believed this was my soul mate. In the 21 years we were married, before the affair, I never once doubted my husbands faithfulness or trustworthiness to me. Well, wasn't I the fool to be had. In one moment everything the marriage was built on came crashing down. We have tried to build it up again, but I cannot even start with the foundation in fear of it falling down again. We did seek counselling from several counsellors and that did help, but only short term. I no longer discuss or even mention the affair since there is no more to be said and yes I am still married , now 28 years.
