Sorry, to hear about your drama.
First get everything worth value and get her name out of it and start selling stuff (her's) like crazy and get a locksmith or visit menards and get those lock changing kit's and if she's got a pet. Sell it and everything I mean everything that speak's money take her name out of the car, house and even the bills. Like she don't exist no more.
Just wait, she will get her karma and no worries you will move forward and she will have to deal with the drama not getting killed by the other man's wife. Diff contact this man's wife and see if you can get revenage together and gang up on her.
