GirlFriend? Well, my guess is ---- Jump for joy, cry and hug her. Tell her you had been bored out of your mind waiting for her to come into your life, and hope she doesn't notice all the pornsites you have been surfing....
Of course, I don't have that problem. I have a wife, and they tend not to bother you too often, except when they want money or permission to sleep with some other guy, LOL.
