Why? If the reason is that you just want to get it off your chest and be forgiven then yes,you are right, Sappp. The reason that I personally would have the need to confess to it sooner or later is because I would have felt like a damn dirty cheat who had made a fool out of someone that cared for me and that I was suppose to care for.
Many people have made the point that everyone hurts somone that they love. Of course we all do, most of the time unintentionally.
If I tell my mother that I'm sick of the sight of her when I'm amgry, of course I've hurt her. If I yell abuse at my daughter just because I'm having a bad day then I've hurt her too.
But these scenarios are very different then being (supposedly) committed to someone that you love and care about, but screwing behind their back - the reasons are irrevelant. And it's not okay to cheat if the other person doesn't ever found out. Because it is NOT okay to make a fool out of someone you are supposed to love and care about.
All relationships have problems and some people just end up not being happy with each other. That's fine, unfortunately it's life.
But don't cheat on that person. Leave first and then go get your kicks elsewhere.
