Trying to parent with a parent who wants to be kids friend

I've been a parent for over 20 years and it was good until the last few years. My daughter, 13, and I butt heads, bad. I've tried to step back and be more patient, tolerant, as well as open. She's rude, spoiled, lazy, and entitled, because of her dad. He doesn't say no to her, on anything. She has no accountability for her actions, He tells her she doesn't need to do chores, gives her anything and everything she wants, plus some. He's allowed her to be rude to me, only sometimes calling her name from the other room without really being present, and only then just saying stop. He's said over and over how he's her friend, not her parent. He says he does it so she doesn't grow up with 'daddy issues'. It's costing me my sanity and my desire to be in this family any more. He's made it team them against team me. I love my kid but I hate what her dad has allowed her to grow into, no matter how hard I've tried to parent her and I feel guilty for this. I cannot talk to him because he feels as he's never wrong, he always right and smarter then me. His words, he thinks he is the next Enstein. Its incredibly frustrating . via /r/Parenting http://ift.tt/2vlV007
