Wife walked away 2 weeks ago has a male interest

[woundedfool]

W having contact with another love interest in front of the kids during separation/divorce is inappropriate.

This is something you may want to address with your attorney. In my case (not Washington State), I was successful in getting a protective order for our child (with relationship to the W's "friend").

Strictly from a custody point of view... if you are doing 50/50 (or around that number), the time she is not around the kids.... is the appropriate time she should be facilitating her "adult" relationships.
