Have you ever been betrayed or pissed off at once?

Oh sure I was. I always thought I am going to be at my cousin's wedding, but guess what they planned the whole thing for September. What a stupid idea. What am I suppose to say to that. I just feel betrayed and pissed off right now. If she would really want me to be at her wedding she should have really thought about it before making this big mistake. I just cant believe these people. Oh well, if we they wanna do it this way fine with me but later don't like go sorry crazy over me.
