Your W is going to spew, kick, scream ... all that. She is wayward. Now she must make sure she paints you as the Ahole to justify what she is doing. You are new to this ... but you need to take a step back and think about this, think about your plan of action and what YOU can control .... which just so happens is only YOURSELF.
She is convinced ... for now... that the M is over, you have officially been fired from your position of H at M headquarters, your desk has been cleaned off for you and your belongings are not being shipped. Accept that .... it happened.
So now what?
You start taking a look in the mirror. Its time to go out and GAL, Detach ... let her do whatever it is she is going to do as you pick yourself up and dust yourself off. Go out and get inot some constructive activities. If you have to .. start small .. baby steps.
For me ... my first thing, very first thing I did after a few weeks of the same self pity me stuff you are going through. I started making the bed, then I made sure the dishes and kitchen were clean before going to sleep. Amazing how a clean house helps your PMA .... then I did bigger things .. joined some sports teams (Football/Softball) ... joined a church group ... made sure I always looked good even if I was not leaving the house... focused on being not just a good Dad .. but a GREAT one.
Start slow ... and all those things ^^^^ they were for ME, not for W nor to try to win her back. You have to rebuild yourself, get your self esteem back, your mojo, your respect ... right now its gone ... but you can and will get it back ... how long htat takes is in YOUR control ... that horse called "Life" just bucked you off ... time to get up and get back on it.
