I'm so grateful to find this site!  My DH and I married a year ago and I moved to his small, rural hometown to be with him.  I had my daughter young and she is grown and living out of state on her own.  My DH has two children by the same BM - a 17 yo SD (soon to be 18) and a 6 yo SD.  We have my SS full time and every other weekend with his BM visitation and part time with my 6 yo SD.  DH and BM divorced when 6 yo was 2 so she does not remember her BPs being together.  She is sweet and fun and I enjoy being with her when she is here.  Things started off okay with the SS.  He was polite enough but is extremely lazy and entitled.  He has very poor grades and no plans beyond his graduation in May.  He bad mouths his father and holds him emotionally hostage for every little thing.  SS also plays the victim role and blames everything on his BM.  BM refuses to co parent and when we pick up my SD she is very unkempt and usually very hungry.  I have caught SS in numerous lies and this morning I caught him taking money out of my purse.  We also caught him several weeks ago taking things from our house over to his mothers.  These are not his things (food, batteries, flashlight - that I know of).  He speaks poorly of his BM and tells me that he can't wait to "tell her off" when he turns 18.  He also does not have any friends at school and the one friend he did have over - he hit the friend in the back with his fist so hard that the friend had to go to the doctor which my DH paid for.  I think there is something seriously wrong with my SS.  Despite being caught lying, cheating and stealing DH does not seem to think it is that serious.  He will have talks with the SS but SS's eyes glaze over and he tells my DH what he wants to hear.  SS thinks that by saying "sorry" that everything is ok.  He is extremely manipulative and sweet talks his grandma and DH into buying him things he does not need and then usually casts aside.  HE did try this with me and I quickly got his number and now I refuse to be swayed by him.  My DH thinks I am too harsh with him and tonight when I blew up at SS over the purse incident and conveyed my fears to DH that SS is NEVER going to move out and stand on his own 2 feet, DH brushed it off and said he won't let that happen.  I am slightly afraid of SS since he seems to have no empathy or compassion for anyone beyond himself.  I purchased a nanny cam to put in our bedroom since I know SS has been in our room and has taken things.  DH says I am over reacting.  Am I?
