The worst feeling in the world is the feeling of betrayal. There really isnt a good reason to betray someone you claim to love. If you dont love them anymore you should leave and if you have issues to address with them, you should address them. To engage in demonic filth and then blame the other person is irresponsible and to go snuggle under the person after you have shared your body with another man really corrupts and moral foundation you might have had for your relationship. Lets not build the foundation for our families on popsicle sticks, friends.
