He's moody, rude, answering back, ungrateful, says hurtful things, angry. last year he was such a loving caring boy, he tells me he hates me and has threatened me. Don't know how to turn things around. I have 3 other children 18, 13 and 8, no worries with them, all good. Any one else share similar experience. I love all my kids but he is so hurtful I can't do anything right
