My 16 year old has reduced me to tears tonight-his attitude is disgusting.He swears non stop ,everything is f*g this and f*g that.Twice today he told me I can't tell him what to do.He is horrible to his younger sister.His Dad had a chat with him tonight and he doesn't care-its all "you can't make me go,you cant legally evict me,if you push me I will push back".Im at my wits end.He tells me 10 times a day how he can't wait to move it,and to be honest I can see the house being calmer when he does move out.Any advice please?
