Sure, write her emails, letters, poetry, whatever. Just make sure you burn 'em instead of sending them. She knows *exactly* how you feel without you needing to keep telling her.
See, that's just it, AC -- I don't think she does.
OK, let me rephrase that. She knows *exactly* what kind of effect her behavior will have/is having on you. She knows *exactly* what kind of effect an affair has on anyone. She's not stupid, right?
And as a result of the 12 months of reading I've done on this subject, I'm guessing that it's tearing her up, too - to the point where she hasn't a damnned clue what to do about the situation herself.
She damnned well *knows* you two need to talk, communicate, whatever. Again, she's not stupid, right? She's simply putting it off in the best way she can because she hasn't - or can't - figure(d) out what to do.
So start over now. After that email, she knows what you want. This is the last time I'll say this - she's not stupid, right?
Now leave it at that. Get on with some of your own stuff. Monitor the situation, but DON'T obsess. Take care of your kiddos and yourself. Be you. Be the NEW you. Let her make her own choices based on what she sees.
The altertnative is to wade in, confront her, make ultimatums, demand talks. Try it. I did. Didn't get me anywhere.
Why? Because it doesn't matter how many talks, emails, letters, whatever, you can't make her do anything she doesn't want to.
