You Sir are a fake and confused jackass and a moron!!  You yourself had inappropriate relationship with your cousin (yeeeww)!  Instead of being jealous, you should feel lucky to even have a gf even if the gf is a complete whore.  This gf of yours seems too nice and too kind hearted for you.  You cannot find such a pure lady even in Nepal nowadays.  If I had a way to communicate with this lady, I would suggest to immediately leave a pervert (going through her personal e-mails, sending her fake emails, talking to her friends.........sounds like criminal activities to me) like you.  If you can change your twisted view of looking at others and be a gentleman, I suggest you apologize to her, marry her and worship her for the rest of your life.  Peace Out!!
