This kind of behavior should be shocking. But having dealt with BM and SDs and their alternate plane if reality for several years now. I can't say I am even the slightest bit surprised.

After talking with YSDs worker, I was informed that two weeks ago YSD was still standing firm on her decision she didn't want to see SO.

Then as of last week she is announcing to her worker and her mother she is spending a week with her father at my brother's lake house. She also mentioned her plans to go boating and tubing on this vacation of hers. Oh I forgot to mention she even invited one of her classmates along as well. 

So my suspicion of her sudden interest in seeing SO and myself was on point. Her motive has been revealed. 

I am intrigued by YSDs mentality that:

1. She can invite herself and her friends to someone's home whom she barely knows without even asking.

2. That her requests will automatically be granted due to her mere existence and genetic ties to my SO. 

3. That I would want to take a week off from work to so and with the kid whose last words to me were to "go F myself and die". 

I enthusiastically told her worker to let YSD know that she is welcome to spend as much time with SO as she likes working on thier relationship. But to not include me, my family or friends in her plans until such time as she has demonstrated to me that she can and will be respectful of me, my home and my rules. I said YSDs behavior damaged our relationship and it is going to take time and effort on her part to mend fences. 

The worker said she will happily relay our conversation to YSD. 

I then sat SO down and informed him of my conversation with the worker. I told SO if he is okay with having a relationship with YSD in which she only wants to use him and take advantage of him. That's on him, but I will have no part of it.  Unfortunately for SO once the worker talks to YSD it is unlikely she will ask to see him since their isn't anything in it for her.
