Fundamental Mandatory Malfunctions and Asshats

Yesterday I went out with "George's" sister, "Frank", for some chinese dining. With this event not being an odd occurance, I enjoyed my lunch and the small talk we shared whilst I gorged myself in fattening food products. What was out of the ordinary was "Frank's" sudden outburst proclamation that if I, Ryne, thought something was up(meaning with "George") that I had nothing to worry about being as it's a small problem and "Frank" was going to be all over it to fix it. So I reacted how any other human would react to such a statement, I worried.

Frank- "I'm going to tell you something without saying it, there's a problem, a little one, but you don't have to worry about it, I'm going to fix it Tuesday, if I don't work."
Me- "So what you're saying is that my relationship rests on whether or not you have to work Tuesday and if you can fix this 'problem'?"
Frank- "No, no, no! It has nothing to do with your relationship................(short pause)
Me thinking- "Que le fuck"
Frank- "Well it does, but it won't ruin it, trust me!"
Me thinking-"Why don't I trust you?"
Me- "Alright....."

So we drive about another mile and in my usual manner of trying to figure things out, I bring up my theoretical problem, and not suprisingly, I hit the nail on the head. I say not suprisingly because of a few reasons.

1. The day that which "Frank" chose for the solving of my unknown problem
2. The statement that it involved my relationship, but didn't
3. A previous notion

Now granted, I could of been wrong, but I wasn't so HA! Anyways, there's a guy in "George's" math class to whom "George" has developed a friendship with. I don't have a problem with my girlfriend having guy friends, because granted I have a lot of female friends and it's not fair to her nor is it my place to judge who she can hang out with. This friend, who from now on will be known as "Asshat" until I deem him worthy of an opinion change, has taken quite a likeing to "George". This doesn't bother me, well not that much at least. Apparently he just found out about me rather recently and backed off of "George" for a bit. However, now he's joking, or so he says, about "George" leaving me and running off into the sunset with him. But I have the feeling it's only the fasade of a joke. Now until I heard this I couldn't of cared less about him being around "George", but now I dislike him in all his asshatiness.........am I wrong for this? I'm not mad at "George" nor do I really fear her leaving me for "Asshat", but it just makes me severly dislike the guy, without knowing him......
