What do I do about my dad?

ok Im thinking that the age diffrents between you and this guy is what is conserning your dad the most, however fathers tend to be more protective over their daughters then their sons, you need to sit down and talk to your dad one on one…its not you that he is not trusting, its the guy that you like…after all your dad,believe it or not was once 19, and he knows was boys of that age are like…he is relating back to himself at that age…his life, and his mistakes…he doesnt want you to get hurt…you are his baby…and as you grow you will find out that the only guy a girl can truly trust through out her life is her daddy..so try to mantain a good relationship with him…talk to him…because he will be there for you through out your life…you do this and he will come around…the more open and honest you are with your parents the more freedom you will have…I was the only girl out of 7 boys and my dad was more protective that any of my friends dads, my life was hell, and I made some realy bad mistakes because I couldnt talk to him, without getting yelled at or put down. and boys were just out of the question…so all I ask is try talking to your dad, find out were he is comming from, why he doesnt seem to like this guy…his answer might surprise you.
