Hello all.  I am new here. I have a SS11, been married to his dad for 3 years and been in their lives for 4. I have never met nor spoke to the BM and we do not like each other.  She said very awful things to DH when she realized he was moving on and I just choose not to have that negativity in my life, so I chose to never meet her. We have SS11 every weekend Friday afternoon through Sunday evening, no formal custody agreement though and we're basically at her mercy. Anyway.

SS11 was playing with BM's sister and his finger got injured in a minor way.  He went to school the next day and before class even started he "warned" the teacher that he simply could not do his work because his thumb hurt too bad.  He is a hypocondriac to the point where he will make a giant deal over some blood on his finger from dry skin or a papercut. Anyway, we are not sure what exactly he said to his teacher, but she called the police and the police went to BM's house.  Obviously the whole story came out and they realized it was nothing. 

Now.... she didn't even ground him at first. We grounded him right away, so when he came to our house that meant no tablet, no TV, no videogames.  He was allowed to draw, play with his hot wheels, or do HW.  Come Sunday, DH does HW with SS and it takes 3 hours.  He gets frustrated because he is just not good at school - any subject.  He won't read anything and I swear when I try to teach him anything he just doesn't even seem like he's listening.  So DH brings up the police/CPS thing and tries again (he spoke to him on the phone the night this happened) to drill home the fact that what he did was really wrong and that he could end up sending his mom to jail if he makes things up. 

BM says when he is with her he has complete blow out arguments with her. He screams and yells and has complete meltdowns. He NEVER acts this way with us, to the point where I can't even picture him acting this way. But she has said for years that he does that with her and DH tries to discipline him but he continues to do it. 

So this morning he got into trouble for something at BM's house and she told him he is grounded from everything - PS4 she bought him for Xmas, tablet, toys, everything.  He told her "you better not do that, I am warning you right now.  Do you think I should tell my teacher about this?" (these are the exact words she claimed he said)

.........I am just gobsmacked at this point.  With us is he fine.. I don't really connect with him and I think he's a very awkward child but he is not bad. We have to remind him to clean up but he does it. He only gives attitude regarding HW but he is usually respectful. He has never yelled or screamed at me or DH. So who is this demon spawn that lives with BM? And now all he learned about the teacher/police/CPS situation was how to get his mom in trouble if she dare discipline him. Should I be worried???????????
