First and foremost, I love my son, but I'm at the breaking point with him. My 16-year-old son has gone from being kind, amiable, and a genuinely good young man to openly defiant, lazy, and demanding. Our biggest obstacle right now seems to be his 16-year-old girlfriend. She has him wrapped around her finger. School, family, and his behavior have all gone down the tubes. She places constant demands on his time, and no matter how many times we talk about getting priorities straight, he just doesn't seem to get it. Today I lost it and said some pretty upsetting things about her (although, I probably shouldn't have), but I can't take her constant control over him anymore. I told him she was bad for him, and doesn't seem to respect that he has his own responsibilities and obligations. He has so much potential, but when he's around her, it seems to fall by the wayside. Honestly, I'm sick of it, and tired of the whole situtation. Any parents who can help would be so greatly appreciated. I simply don't know what to do anymore.
