tadpole1025...I know that is what I need to do, but I don't know how to turn off the switch.
She just called asking if I was going to dinner tonight with her family for a brothers b-day. Part of me wanted to say I had plans, but as ForeverYoung says just go as "whatever". I have to eat, but I also want her to see that I can be strong enough to show up with her entire family that knows what is going on. I think she was expecting me to say no.
You start by accepting you have been fired as her husband. If you choose to stand that's fine but you do not go into the office and look for emails nor continue to do the work you once were getting paid for ... IMO this includes putting up the front that you are married for her family. You have to find activities that keep you busy, help rebuild your self esteem and confidence ... working out, going for a run/ride .. whatever .. things that are constructive and make you feel better afterwards.
