Whoa almost had an OPSEC failure there Pain!!! Glad you changed that.
Don't bother to tell your W she can't take your daughter to OM's house. You have no control over that. Why bother? What's going to happen when you have this convo? I'll tell you: you're going to come off as controlling and she's not going to listen to you.
And even IF your W agrees to this to your face, what are you going to do when you find out she brought D4 over there again?
Move on to something more productive.

It is not things that bother us, but the stories we tell ourselves about things.
