When your man cheats online, it can shatter your self-esteem in ways you may not even be aware of. Suddenly, you may be doubting your sex appeal or questioning your ability to be tender and loving. Because all these insecurities bubble-up, it's best that you 'unplug' from him as much as you can (that also means no games, silent treatment, punishing him, ignoring him for results-- just mental and physical disengagement) and take care of yourself best you can. The rest will work itself out over some time. You may feel confident enough to leave after a few weeks or months of taking your life back or he may respond well to this new dignified, heartfelt, ladylike you who doesn't take any crap from a cheating man.
