<human>: So I have been buried by my own worries and second guess the last 24 hours or so.  I have been dating the girl of my dreams for almost 4 months now and there is not one single thing I would change about her that I can think of at this time.  She has helped me with anger and resentment as well as arguing to the point of frustration.  

Now that seems good and wonderful but here in lies the problem that I am facing, the conflicting thoughts, if you will.  My girl is small and loves to have fun with her friends, she was actually once in a sorority but dropped due to time constraints of school.  But she still has close friendships with  her sisters and one of her sisters has invited her to go to a fraternity party in a week or so, a fraternity that they know well so I'm not infuriated and out of my mind about it.  Unfortunately, I worry that something will happen.  This worry arises because over the summer while my gf was intoxicated and out with friends a man other than myself tried to kiss her and succeeded in touching lips.  She promptly said sorry I have a bf and pulled away.

I'm really glad she told me and was cognoscente enough to realize it was wrong but it really hurt my feelings and I felt that it could have been avoided had she not been so drunk.  So basically I am afraid something like this will happen again or worse.  She is a tiny thing 5'1" 110lbs and it would be really easy for someone to just take her away if alone and in a dark area.  Maybe I'm worrying too much... 

Please what should I do and for those who tell me I need to not stress it so much, can you please give me some alternative to help me get over it or take my mind off of it!!

Can you provide a brief rundown of the text in within 3 sentences?
