Advice on my Scenario Pt. 22

[OrangeK]

Also, I have asked yet again to have her please get a bed for S3 if they will be sleeping at OM's house.
S3 complained about it again last week. She slept with S3 there Tuesday and Wednesday night.
Yet she continues to deny and lie about it.

"I am dissapointed that the co sleeping in your boyfriends bed continues. If you are living there please get a bed for S3. As i have said before, for him to share a bed with a strange man is not emotionally healthy for S3, nor is it morally appropriate. I would have thought you would put the developmental and emotional needs of S3 before your own convenience, but sadly for S3 that doesnt seem to be the case."

I am done walking on eggshells for her. It would be one thing if she openly admitted doing this, then we could at least have a discussion about it, but the fact that she continues to deny it and lie about it is exceedingly frustrating. How can one co-parent with someone who will make poor choices on purpose and deny it?
