Daughters with Strict Dads and the Moms who try to even the playing field.....

I am a young mother. I had my oldest three months after my 19th birthday. Now at age 35, My oldest daughter is 16, the middle daughter is 14 and the youngest daughter is 7. Yes you heard me right, three girls. It's why I stopped having children. one they're ridiculously expensive and two, I don't need another lady in my life. I love my girls, don't get me wrong. and I love love love children. I just want to give the three that I already have a great life without adding more complications to it. I'm not a single mom, I've been with their dad since I was 18. We are not married (if it's not broke, why fix it?!) and we have struggled as young parents, young relationships and just being young and dumb. And the struggle is far from over, it's just now becoming a little more even. Dad is a true mexican father. He keeps his girls close and his daughters closer. lol. They're not allowed to go out very often, or stay at peoples houses. However, they can have as many friends over as they want, and we try to fill the house with snacks and fun things to do to keep them busy. But really, they're teenagers and they want to go do things. Especially the oldest. She's going to be a junior in highschool and she's not even allowed to have a boyfriend yet! She's a very good girl. She helps around the house, she cooks, she helps with her sisters. She gets great grades, and doesn't talk back often. (she's still a teenager, i'd be lying if I said she NEVER talked back!) I've tried to have a talk with her dad, but I believe parents should stick with each others decisions in front of the kids. I can disagree behind closed doors, but united parenting is important. SO instead I try to make things good for both sides. I drop them off at the movies, pick them up. If a boy goes to meet them it's not my business, as long as they are there at the movies when i show up 20 minutes early to pick them up, i'm happy. I'm not for premiscuity, I think serious dating should be saved for college. But I don't think holding them back when they are ready is beneficial. I'm trying to raised old fashioned girls, in a modern world. I tell them it's okay to be modest, and not post half naked selfies. You're still beautiful with clothes on! I'm all about fashion, makeup, and beauty. I just don't think you need to starve or wear skimpy clothes to look beautiful. What are your experiences with teenage daughters? I would love to hear other experiences!
