The way she goes on about it is intenstly disrespectful to Will and their relationshjp. Will should have split with her long ago if he had any wisdom and wanted peace of mind. He didn't and now he's a cuckold.
Anyone would feel this way.
You are a liar if you wouldn't feel some type of way if the partner you are in love with drones on and on about some guy/girl. Talking about they have my soul. Your kids talking about "come back to life to make mom/dad happy". I don't know how I could handle it. I refuse to say Will is a better man than me for dealing with it for so long, because he's not, but I will say he is a different man than me.
Maybe I was just raised in a traditional household. My parents do everything to exalt each other and have each others back. Even straight up white lie in public about each other in order prop the other up.
That family is strange.
