I agree with Helen in that we have been through tough things, and speaking for myself, having seen and experienced such terrible betrayals and behaviour from many of those around me, I am now at a point where, like Helen, I would NOT stand for any rubbish, cheating, unfaithfullness, deceit or lying from anyone.
Having had my mum kill herslf because of her turning a blind eye to my fathers long affair,and the damage it caused her, I would never do that myself. My second husband (who is a lovely godly and completely faithful man) knows that if he ever did anything like that, the marriage would be over, and if I cheated I wouldnt expect him to take me back either,(though I suspect if I was repentant he would)I doubt I would divorce him, as I am 55,and I really have no interest in any other man, but the marriage would be irretriveably damaged, and I doubt that I could ever have sex again with him.
I know this comes over in my posts because I HATE to see so many taken advantage of and treated so badly .
I suppose there is some of that British bulldog spirit as well, and that strength many of us do seem to find during bad times.
