After reading your one-liner, it makes me very difficult to comprehend how you could be so sure on your claim. Having passed quite a deal of time as a married man, I have seen much of experiences one goes through to maintain a happy married life. For a marriage to be successful, both the wheels must turn in unison. Doubts on each other have no place at all. And let me tell you it's not always the woman's fault when matters come to losing trust. There are men around who simply don't have the psyche to understand females. Not just that, there are some who are by nature hypersensitive and watch every move of his wife through a hand lens and look for any sign of infidelity. I had a colleague here several years back who would get very upset when he would make surprise calls to his wife back in his country and not find her present at home. He would keep wondering where she had gone to or who could have come to his home. If you fall into such category of men, then you are simply making someone woman's life miserable, that's all.
Suggest you correct yourself first before you come out on a social website announcing that your wife is cheating on you. No proper sane and matured person would ever take such a wild step.
