NEED HELP do you have any other ideas how I can help my daughter and I with this issue?

WOW, how is "todays" parenting doing for you? lol Go old school on them. Whip her azz if she disobeys you. Talk to him while sharpening a kitchen knife or cleaning a gun. Let him know you mean business but in no way make a move like you will use it on him. She is 14 = she will rebel but later on she will realize why you did what you did. Be prepared to be hurt mentally with what will come out of her mouth. Plant a couple cactus plants under her window. Gotta do something asap or we will hear later from you about her pregnancy. Good Luck.
