You will find in the christian walk you have to have 2 things going on. 1) is your total sold out life to God. Thi is your 'real' life,your refuge,your safe place,where all life,energy and virtue come into your being.
The other is the natural walk.Wife,family,job,commitments,repairs,etc.
You have to apply this. It is not incidental,or automatic.It is your state of being,and state of mind. It becomes your inner constitution,or 'your center'.
Now,your immediate job is to forgive her. (seems impossible),but this is how you do it;
You say to yourself "I forgive her right now,even though it seems fake,i say to heaven,"Lord I do forgive her,now Jesus help make it real.Give me this superntural gift I need to be obediant and forgive."
You say it over and over.You make it your ammbition. God WILL HONOR your steps. He will see your heart.he will see your effort.
People are fickle,we all are. You just found out where to invest and where you must apply RESERVE. You don't ever put your total affection on any human.Even your wife. She could be gone tomarrow,and where are you? In the ditch!!!
Use this time to invest in your walk and make it such a walk that the devil and every humanoid be made lesser and Jesus rule every cell of your being.This is done through worship,meetings,and getting around anointed remnant believers.
