What are some boundaries that you have in place in your home that are meant to protect you from bm intrusions?

What boundaries do you and/or dh try to not cross to keep out of bm's hair?

1 we do not allow bm in our home, we do not enter bm's home

2 try not to answer the phone when it's bm

3 try to keep all conversations in text form

4 if there are any schedule swapping dh gets the time to be made up with sd first then bm gets time with sd (otherwise he will never get that time back, because bm is a pathological liar and always takes dh's time away if she can)

Things we try to do to stay out of her bad side

1 if we run late let her know (has only happened twice in the 5 years compared to her countless times without her letting dh know)

2 rarely ask for extra time (has only happened twice ib the 5 years, compared to her countless times)

3 no nonsensical phone calls. Bm calls to let us know that sd got a 100 on a spelling test, dh just dropped off sd, she already told him. She had also called to tell us that sd has arm pit hair (this was 2 years ago, 2 years later, she had yet to sprout any arm pit hair... I think it was jacket fuzz in her sweaty arm pit)

4 we don't stalk her Facebook page. Sd has told me that bm made a comment that she saw on dh's page that sd and dds wore too much make up when they dressed up like they were in the 80's and they looked like they were street walkers (I made them over because sd said she wanted to she had fun doing it with her mom before, and I remember doing it with my mom) so I made over all the girls over and did their hair and make up and dh took a picture and put it on his Facebook. the crazy part is dh blocked bm, sd said bm had a friend show her dh's page.

5 we don't bad mouth bm in front of any of the children. I say any of the children because I know that as children they may not be add in control of their emotions and may repeat something one of us say in the heat of an argument. (Whereas bm is always bad mouthing me to sd. Saying things like I'm more closely related to a monkey than normal people, as much as that made me want to cry on the spot, I couldn't allow bm the satisfaction. She tells sd that I made them over to look like street walkers. She tells sd all sorts of horrible things all the time.)
