Perhaps I recommend to "Pause" the divorce to let things settle down a little bit before making such a life altering decision? Or, perhaps I cancel on her at the last minute and tell her that I've had a change of heart and have any types of talks with her
Dude, she is involved with another man. Period. Why pause? On the hopes of it somehow winning her back? No, that won't happen. Seems that she is intent on this, so just do it. It'll hurt more in the long run to keep stringing the inevitable out. She's open about the affair and doesn't care what you think...that is so telling. Good grief. Doing whats best for you doesn't involve pulling any last-minute straws in hopes of winning a cheater back. Sorry, but won't happen. And, why would you want it to, anyway?
Why have any talks with her in the first place? Your agenda and hers are two different beasts. Sure, some will tell you to roll over and talk to her. Why? Why put yourself through the misery and heartache?
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
