How to get my dad to relax about my boyfriend?

Me and my dad have been close ever since my parents split he has favoured me out of me and my sisters .
I have always been the bad one but I never caught . my parents are always going mad at my younger sister . how do I stop this ? .
I have never...

taken a guy home to dad for a while because last time I did he threatens them as soon as I leave the room
( in a joking manner) .
my dad totaly humiliated me in front of my family and he wont give me and my boy any time to even kiss without him watching .
I no I am his little girl but I am growing up and I have a boy friend . how do I tell him to back off and the worst thing is that me and my boy have done everythign togethter but dad gets defencive even when I talk about kissing him . ?
HELP
what do I do ?

Tell Him That Your A Big Girl And You Can Handle Yourself. Tell Him That Your Not A Little Girl Anymore And You Need Your Space. He's Just Being Protective Of You That's All. You May Not Be A Little Girl Anymore But You Will Always Be His Daughter.
Hope That Helps.

There won't be an easy way. Your dad has to get to know him in his own way is all. My dad would do the same thing. It's all about them. You seem to be only 13 so that could be another reason. Don't you think?
Good Luck

FIRST OF ALL RESPECT YOUR PARENTS. HES JUST UP SET CAUSE HE KNOWS ONE DAY HIS LITTLE GIRL IS GOING TO GROW UP FOR GOOD. AND DADS NEVER WANT THAT .

well just talk to your dad about it dont get rude with him and dont talk to your dad about you and your boyfriend kissing thats is a big no... no dad wants their daughter to grow up fast and thats just dads they want to know your safe and protected thats it

thanx for that
