I want to "forget" my wife
Why do you want to forget your wife?
She is just a terrible person. All she does is make me angry.
Spouses are supposed to care about one another and have their best interests at heart. If you no longer care about them and want to forget about them, then move on and get a divorce. This way you can both put your relationship behind you and start anew.
I am going to just move on without divorcing her. I just want to do what is going to make me happy. Don't care if it is technically cheating.
That's awesome, you definitely need to divorce your wife if you want to move on. You shouldn't just ignore and forget about her.
