Congratulations, Oogly. This one got to a high-enough tier on the funny meter that I had to jump up and crash the B-room door to pee.
Listen, this could be a lot of things. You might have done something damaging if what you said here is correct:
(I lost it here... kaleigh (which she totally spelled wrong) is my girlfriend, who I would do anything for... I swear, if I were to be talking to this girl in person... I would literally slap her till she bled.)
If this is true, depending on how jealous your GF is, and how serious it is, you could risk having this girl show the whole conversation to your GF, if indeed they are friends. You might have some explaining as to why you were talking to a strange girl on an IM in the first place. To tell the truth, it could all be your GF and her friend trying to cause some kind of soap-opera havoc.
(Disclaimer:The gist of this idea comes from the well-known fact, That while you are dating, Your whole life and it's secrets become known to a GF's inner circle of friends. One of the inner circle will be you GF's Sec. of state, or manager of internal affairs, who will have as much intel on you as possible.)
Consider this a test of whether or not you are comfortable living at the center of a conspiracy to ridiculously test your devotion to your GF. This may be out of line, but watch the look on the *****'s face when your GF tells her Best that your last date ended in the back seat of your car after curfew, and not by just saying 'goodnight' 30 min. before daddy wants here home.
At that point, her best has lost( because you won the hand of your GF) and slowly, you will completely occupy the territory once held by your GF's best, such as most intimate secrets, first phone call and most phone time now goes to you instead of Best, etc.
Watch the tactical mistakes, though! Don't fall for a troll like that again.Might be a pettilly-jealous best friend trying to out-manuever you and cause probs between you and your GF.
P.S. Alot of this Had the input of my wife. It sounded WAY to fishy to her.
