I'm inclined to say, wait a bit longer. He's admitted to having a dark side and he's told you what the EA is like. From the conversation that you two had, he's recognizing some of what is going on w/him. He is speaking the mlc lingo.

Do you think you can wait a little bit longer or do you feel it is absolutely necessary to boot him out? If you can hold on a bit longer, just ignore him as much as possible and continue as you have been. I honestly do not think he wants a separation and/or divorce. He is very much aware of how much the family unit means to him.

I do think he's been as honest as he can be w/you concerning how he's feeling right now. BS? I don't think so...Will he change tomorrow? With the mlcer anything is possible. The question is...do you love him enough to want to hold on a bit longer?

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.
