If your wife brings up you trying to hold onto the marriage and her hit her with this :
"You are trying to hold onto me and the marriage, well it wont work!!!"
You think I want to be married to someone who acts like YOU? What I am DOING is trying my damndest to NOT be YOU. I am OK with divorce, I just don't want an UGLY divorce despite your efforts to have one. YOU are trying to hold onto an UGLY divorce and I wont' accept that. Let the anger GO will ya? It's not helping this process, its just making you look bad.
