Find myself on my own with my three teenage sons. Missing my husband even though he let me down big time and eventually left - needs to take more risks with his life - has fewer years to live than already lived blah blah!Has been having affair for past two years (spending lots of money on smart hotels) and had affairs previously, one of which I knew about when the boys were small, but was determined to work through because too much to lose. He has been my only 'boyfriend' - met at uni and together since then. Many good times - he is my oldest friend.Little conflict is marriage , therefore a surprise for the boys. Have had to sell family home and now settled elsewhere, all within 3 months. Now taking stock - exhausted. Have I done the right thing? My sons are great and never wanted to put them through all this-I place a high value on family stability, but at what cost?
