How to get my girlfriend's parents to like me?

im 14 years old and in ninth grade. I have a 15 year old girlfriend that is also in my grade. we have been going out for a little more than 4 months. here mom is divorced and has moved into her boyfriends house. her boyfriend is a 50 year old "old italian" and has lived by himself all of his adult life. so theoretically they are not going to change him. since he owns a masonary business, has dial-up, and works out of the house, my girlfriend isnt allowed to use the phone at all. I see her in school and on the few dates we've been on. but thats starting to get rarer and rarer. but thats besides the fact. since they live in HIS house they make no decisions what so ever. her mom is to...im not even sure what her problem is but she wont leave and he is completely uncooperative. her mom just goes along with what ever he says and he lies most of the time. its almost like hes pinning them against eachother and using me. for instance one day she had a detention. I was at a track meet. he told my girlfriends mom that when he went to pick her up, that I was there and she ignored him to be with me. this is getting out of controll. I think...no...I KNOW im in love with her and I wouldnt leave her for anything, but they are making it hard and almost impossible for me to see her. my biggest worry is that they are going to transfer her (we go to a private school)
I dont know what to do, I've tried a lot,
me breaking up with her would hurt her so bad emotionally and I love her to much to put her through that.
PLEASE!!! somebody help me

who cares what the parents think, as long as she loves you, and you love her? nothing should get in the way... dont let them be a barrier to your relationship, because that will make problems start to occur. :]

I agree with superfresh. make sure to do what your heart tells you if your heart knows you like this girl then don't give up stay strong be a rock. (lol)
hope I helped
