Well, I'm no expert. But the proof may get you full custody of the kids depending on the judge. However, I know you just want to fix things and that is what is best. Just whatever you do, don't make it look like blackmail to her. That will not bring her closer to you.
You might start with just talking to her and letting her know that you know about the affair and that you do have proof because of how she was acting. You might tell her that yall can work through the affair.
Of course, I say this and it didn't work for my W. Some have told me that while the A is going on, there is nothing you can do except keep back and work on yourself. Then when it ends, be a great option. The typical A lasts about 6 months. But since yall are already talking to lawyers, I don't know. You have to watch out for yourself and your kids. So you have to use it in your favor when it comes to court if it comes to court. But heading it off before that point, could keep it from going to court. Then you don't spend thousands of dollars fighting it out. She may realize that you have her and its in her best interest to retreat from the divorce.
I really don't know. Wish I could help you more.
