Your h isn't quite rational and trying to have rational conversations w/him are going to drive you nuts.
Notice how he justifies continuing a relationship w/the ow and then continues on in saying you should continue to do the laundry, etc. That's cake eating. He wants the best of both worlds.
He knows that if he goes to counseling he's going to be asked some very painful and pointed questions and he doesn't want to have to think about them and respond to them. He also knows that the counselor will see right through him and he won't be able to BS his way out of the session w/his answers. This is so normal in the mlc world, i.e., the excuses for not going to a MC, etc.
Please take care of yourself and do something extra special for yourself today.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
