I am the mother of the stbx husband and I got along great with the mother of my grandkids.I take care of the grandkids daily and have since they were born.Now there is a new BF and the mother says since they will be and are a family she wants him to make the descions with her.I even had to wait for her to ask this guy if my own grandkids could spend the night with me.She has them calling him daddy and he is an ex con,who was on drugs,and has a record a mile long,as he has admitted.Ipersonally feel that the parents who brought that child into the world should be the ones to say what goes and what doesnt.My grandchildrens mother is demanding full coustody with supervised visits for my son,yet she lets the new BF take care of the children.I was raised in a stepparent situation and it is rough on the children too.We were forced to call this man Daddy and he ended up molesting me for 5yrs.
