I feel for extremely nice people like you nam. There are the idiots of the world that thinks being nice is always saying "yes" to them. Hey, here is someone I can use!! She is definitely using you and your child may pay for this if you let this continue. Sounds like his mom is enabling her son for his psychopathic actions. This is a dangerous situation for you and your family. Being nice is one thing, but please be wise along with it.

You've done enough and if it causes estrangement with this family; you have gained and not lost anything but headaches. Allow you mom's instincts to kick in to protect your own; and get this boy and the user out of your life. We can't be there, be liked by all people and that is reality. Hugs, bj
