My 15 year old step son is driving me crazy!!!!! He moved in with us full time 6 months ago. His mom has only had him over twice in the last 6 months, this weekend she claimed she had the stomach flu and was very sick but she was out partying all weekend and was dumb enough to post it on FB! . Because he was failing all his classes he has been doing online virtual school and since I'm a stay at home mom I'm with him all day everyday! Along with my other 3 boys(my hubby and I have a 7 yr old, 5 yr old and 7 month old) We had a good relationship before he moved in but now that he lives with us he constantly gives me attitude and talks back. My husband and I started having problems because I'm not ok with his son talking back to me. How can I fix this? And what about BM?
