We are all human and we know what we should do but there is this need to poke the sore.
I know how this feels , another punch to our hope , and none of us would be here if we did not have at least some hope.
In reality nothing has changed. H has been caught and has told you a lot of stuff to try and validate/ justify what he has been up to. Try not to buy into it , he probably dosnt believe half of it himself deep down.
I think hes still in the Game for now , I tend to think if they are still trying to keep secrets and not be honest and up front they are trying to keep the path back a little clear just in case.
The question will be how long are you going to stay in the game?. My advice to you is similar to what I should do ( Should being the operative word ). Let him go , realy let him go. Think about yourself and do the best you can for your boys. do something different and unexpected.
You know all this of course . and avoid R talks , they will be negative while there is an A going on and PMA draining.
Work on your Goals , and thats easy to say , hard to do. I have had an interesting development that makes things just a little clearer but more confusing as well.
