If WI is a no-fault state you have no say in the matter. If she wants to file there is really nothing you can do. A spouse does not need approval to D in no fault state. Sure you can contest different aspects of it but all that will do is tick her off and cost you a lot of money in attorney fees.
I'm sorry you're going through this but it really does get better once you have some closure on what is happening next. Once my WXW filed I then knew where we were headed. Once a final date was set I then knew when it would be over. Once that day passed I now know the next step is to refi the house and she moves out. Having the dates, not being in limbo anymore helped create some peace. I'm not saying give up or that it's over but The truth is it was really over when she brought OM into the M and continued to choose OM over you.
Get up.....dust yourself off.....and be the best Trumpet you can be. If she is choosing OM over you than she doesn't deserve you
