Ok so fiancés actual mom has been in jail and arrested numerous times, spent 6 months in jail in 2015, and still continues to do the same things she was in jail for and associate with the same people. Am I in the wrong for not wanting her to share anything about our son on any social media including his name, due date, what hospital I'll be at, ect. Because I don't want to risk anything happening to him if something goes wrong with what she does? Am I also in the wrong if I tell her she can't watch him alone or even come to my house to watch him because of some of the charges she still has? Am I also wrong for saying if she keeps doin the things she was told not to do in regards to ultrasound pictures and information we have personally given her and told her to keep it off social media that I will not allow her at the hospital or any where around him when he is born?
