| | Re: Divorcing after discovering husband's affair. Need help :(
I am really sorry for your pain. It's awful.
Right now, you need to think practically: you need to lead by example because your husband is not being a good leader. Do not badmouth your husband in front of your son, do not get emotional with your husband and do not pull the same thing you husband is by involving men in your life. Be the light that guides your son because, again, he's not getting that from his dad.
File for divorce, child custody, child suppot and alimony if possible. The sooner you do this, the better.
Do not get into heated debates with your stbx. All business from now on. He made his choice. Now you need to not let him see you sweat. Only discuss co-parenting and divorce issues with him. Distance yourself as much as you can from him. Get busy with a new hobby, exercise, call up old friends and surround yourself w/ a good support system. Get therapy if you need to. Read a book, try something new.
You deserve better so do not chase your stbx. At all.
Carry on with your head held high and don't ever look back.
