I screwed up REAL bad!!!!! I need help ASAP!!!!

My girlfriend put me through a test to see if I was truthful. She signed on under her best friends screen name. I didn't know who it was at the time so I played along. She asked me if I had a girlfriend and for some messed up reason I said no. I was not thiking clearly when I said that. Now she's debating whether or not to break up with me. We both basically planned out our entire lives together...I honestly do not want all of this to go to waste. If I lose her....I might end it all that very day she tells me we're over. I need some serious help and fast!!!!!

Dear Richard,
oh hey ur problem sucked and I can see why your gf would be alarmed. My advice would to just be talk to her and explain that you weren't thinking straight I mean if you have huge trust in your relationship this shouldn't be a problem. Dont let a lil mistake like that break you guyz up. It kinda seems you guyz dont have a huge amount of trust otherwise she wouldn't of tricked you. Two wrongs don't make a right but what she did was wrong. Just talk it through and tell each other how you feel. you gotta keep the communication barrier open. Godd Luck and all the best 4 both of u

xxoo,
