Another thing you want to do while she's home is setup your computer to send you phone calls every five mins...
This gives you a way to IGNORE her if you want... you half listen to her and half look at your phone like what she has to say really isn't all that useful to you.
If you need a break you can say "One sec, I gotta take this one..."
etc...
It puts HER in the defensive beucase rather than you standing there taknig a beating, SHE has to fight for YOUR time and attention...
Leaves them completely off guard... They hate it, but it does teach them that they ain't the prize they think they are...
Well they can be a "prize", if we spouses allow it. Of course if they are cheating, thats not a prize anymore.
