Exposing a child to infidelity separated or not is inappropriate... NO AMOUNT of TIME makes a difference there.
If he's still married and there is no divorce even filed yet then he has no business exposing DD to OW... I don't care if the separation has been two weeks or two years.
Exposing your DD to ANYONE should be something you BOTH consent to or it doen'st happen...
NEITHER of you should have the other spouse introducing DD to ANYONE without the other spouse approviing and having prior knowledge...
Please forgive me for jumping on your thread.
I am in the same situation with my wife: we have been legally separated for four months and this past week she went to the summer cabin with OM ( they work together) and introduced him to my children and my wife’s Aunt Uncle Mom dad brother and sister. OM brought his kids as well. My eight year old D said they stayed the hole three days.
My apologies again for the interruption. Desperate times
My thread Mt wife introduced OM to my children this week.
