My girlfriend lives in hawaii and i want to visit her, but my Father says i am blinded por amor and won't allow me to go.

Continue to ask your father, but don't be whiny or ask constantly. Ask him when he's in a happy mood. Save up your money, plan your trip and show him that you're ready to go. Since it's a go with your mom, maybe get her to come with you. If your parents are on good enough terms, maybe you could make sort of a family trip out of it! Good luck!
