Frank, my thing is this. It's not about what she is doing, who she is talking to, or if she dumped the OM. It is about her being there to help with the girls and give you time to focus on getting your own [censored] together.
So how about we stop with all the contemplating her motives, wondering if she is still with the douchebag, and focusing on anything but yourself.
I agree with Amy, she is a fruit loop. I will call you today....
