C,

Removing her from the MB and packing her stuff for her shows her that you know what is going on and you are not going to sit back and accept that your W is sleeping with other men.

I would also contact a lawyer and see that since your W is staying with her friend for the week if you can file abandonment charges which you can use in the divorce settlement.

There is a saying around here that things need get get worse before they get better.
