I've posted once (I think) here before several years ago when everyone was very helpful and am now at my wit's end with my soon-to-be-16-year-old DS in year 11. We've had a lot of fights since the start of the school year when he decided to give up on schoolwork. He turns a corner for a few days and then goes again. He's been exhausting us, and his school have, I think, already gone above and beyond the call of duty in trying to get him back on track. However, all that is actually an aside. We've struggled for years with him using language we find unacceptable. This evening in an argument about how behind he was with his art work he yelled at me "Fk you, you bh! That really had me floored and I've been speechless all evening. I'm astonished he thinks that is an acceptable way to speak to his mother. The fact that he doesn't think it warrants an apology means I'm now unable to speak to him. I'm just stunned, furious, disappointed and tearful. Am I behind the times? What to do? Grateful for all and any input.
