You need to get to a point of indifference towards your W. Try to shed the anger and resentment. Not healthy. That is something that I have been working hard on. I refuse to be like my EXMIL. Bitter her entire life that her H left her when EXWW was younger. MIL never moved on and lives alone and is very emotionally and mentally unhealthy.
Not saying you would end up like that. There is just literally no point to be angry or resentful. This is where you focus on yourself. Does it benefit you to be angry and resent your W? I doubt it. So let it go. Because there is literally nothing else you can do about the situation besides accept it and move on with your life.
