MLC with a side of infidelity

[Optimust]

She wanted to talk last night when I got home from work. She was pretty mad after finding VOR snooping device, but couldn’t argue the fact that I used it to try to get some truth, because everything she has said for the last month has been lies to cover the A. She immediately calmed down, and got to the heart of the matter.
She wrote a note explaining that she was going to file for D, so she could stop the lying and the hurting. She said she will cooperate so we don’t go bankrupt. She says I deserve to be loved more deeply than she can. She says she has tried and prayed and it’s just not there, and no amount of counseling will help(never tried). “please just let me go so we can both have a chance to find some sort of peace from within”.
I talked with her about separating instead, so as not to cause undue damage to the M, family, and kids from issues that can be resolved. I told her that I didn’t want to pressure her in any direction, and that I felt that she should try not to let the pressure from OM to kill our M effect her either. We ended with her saying she couldn’t talk about it now, she had a lot to think about. I know she went to lawyer, and he is drawing up some stuff for her to sign tomorrow or Thursday. I was hoping our talk would help some, but her BF told me that when they were at coffee today that W seemed pretty adamant about her decision.
So here I sit, feeling like a sitting duck, just waiting for the hunters to show up, I’m thinking I will be served some time in the next week, and then have to start that nightmare process.
She has turned her back and is running from everything she knows, me, our families, her faith, and I’m thinking at some point soon her job, so as to take one closer to OM house(over 1 hour away). He is the only person she feels she can turn to at this point.
I hope you guys will help me through all this, I don’t know how I’m going to do it, but I have to for my DD’s sake.
