MLC Wife exposing little kids to OMs

[mile_high_PMA]

I did talk to my W when she came to pick up the kids today and I asked her in a very nice way if she can avoid having her SO when the kids are present. She immediately turned defensive. She told me that she never does anything inappropriate with her friend when the kids are around and she never makes bad decisions (whatever that means). She also mentioned point blank that my outlook on setting good examples for the kids is a matter of my opinion only. She definitely showed me the finger but I also saw that she was visibly shaken up.

Either way, I need to decide if I want to proceed with legal action, which means filing for a D myself. I was really hoping that I would wait till she files the papers since I stand for my M. I hate these situations! Only thing remains steady - I am moving on with my life.
