Loving the attitude, relieving him of his family responsibilities due to his behaviour and the fact he sees his AP/LO as his primary focus is great. What will he do? Eventually he will want to know about all the things he's missing out on it might not be for a while but rest assured it will come.
Until then let them spend as much time together as they want this will only escalate the fog lifting and the reality of their actions hit home then who knows the cracks might appear but will you be bothered? I personally feel my sitch is just a little more advanced than yours probably a month or so and its interesting to see how much similarities there are!
I am finding it hard to truly let go but the longer this goes on the easier it gets BUT I feel every time I allow her to come back into my life I go back a month or so so really am trying to fully detach.
Remember when you HAVE to communicate be that confident happy person who's getting on with her life and not giving a jot about what WS and his AP/LO are doing.
Have fun and well done.
Mark.
