I know others see this differently, but because I have moved beyond DBing, [although I am strongly pro marriage] I have to ask why you would want to be with someone who doesn't have many friends, and is keeping an OW in the wings/on the boil, just in case things don't work out between you and him?

It might make sense to a warped MLC brain, but to most people it is an appalling atitude. If he cannot take a chance on it working out with you, he will run back to OW at the first sign of trouble. He needs to pull up his big boy pants, and take a shot at commitment [with you].

I think you deserve so much more than this mean spirited and selfish attidue, mlc or not. Your life, Cas, and I would support whatever you decide, but these guys are masters at suckering us to see the world from their warped viewpoint. There really is a difference between compassion and enabling.
