How can i show my girlfriend's parents that i'm a good guy?

My girlfriend's parents HATE me and threatened to put a restraining order on me..
I've been dating this girl for 4 years and I moved to Hawaii and moved back last year and started dating her again so I guess like 9 months...and her mom doesn't like me...

because I don't have parents and she thinks I lie because ''how can someone with no parents be disciplined and settle and what not? (They passed 2 years ago) and she just assumes stuff...so if that wasn't bad enough, she pulled up our AIM convo's about sex. I think I mentioned handcuffs and a blindfold and she printed it out haha so that in itself killed all chances w/ her approval from her parents!
I don't wanna give up on her. We are crazy about each other and I have a business and make great money and her parents think its all a lie. What do I do?

it sounds like you really like her, you really need to show them how much you care about their daughter. try taking them out to an expensive dinner in order to show that you are well off in life, and ask them for their permission to date their daughter during dinner

Simple, if this girl wants to be with you bad enough she would stand up for you and fight for you regardless of her parents!! you have done wat you need to to prove it, its been years and they still have issues so its their issues. You know your a good guy and make money and have values and morals and if they dont wanna see it thats their problem. If your gf sees it thats all that should matter. What i dont understand is the sex convo....who pulled up the convo and showed her parents? if it was her then that was the biggest mistake and i dont understand what she was thinking!!! cos she ruined any chance herself of her parents liking you.

darling having a great business and a great life is no basis for winning the approval of your intended victim err, future wife's parents.

leave her alone and go find someone who has a family that adores you. cut your losses. put a fork in it. yes i know what a thrill it is to be naughty and so on, you get off on this but it really is a waste of everyone's time.

The best you can do is walk away don't brake that parents and daughter relationship, let her flight if she comes back she is yours and if she doesn't she never was and maybe God has the right person for you, one day you'll be parent and you will know what you will do for your love ones..
