Dressing Up, Dating and the Goodnight Kiss

Whenever I have something to look forward to, I get excited.  I like to pick out what I'm going to wear, how I'll wear my hair and even what perfume to put on.  But sometimes I commit to things and regret it later and then I dread the impending date or party so much that I'm tempted to cancel. 

You guys always ask me why I'm still single - there's many reasons.  The main one is fear of commitment.  You guys should know what I'm talking about because it's usually guys that have this problem, if in fact it is a problem. 

Anyway, I have a date Saturday.  Don't worry boys, it doesn't look promising in any way and honestly I got goaded into accepting this invitation by my friends who thing they're helping me "fix" my life.  No one gets that my life is exactly as I want it for now. 

So while at this party the other night, my friend's husband introduced me to his co-worker.  He was really nice, but I felt trapped.  I like to meet guys in my own time.  I was there to have fun with my friends and now I have this total stranger watching my every move all day long.  I felt like meat on a stick.  And while I might find that hot when I'm on NF, it's really unsettling in person. 

The problem - my date is Saturday night.  Today is Tuesday.  I met him last Saturday.  He's called me three times already - twice on Sunday and once yesterday.  I feel smothered. 

So I need your help - Do I ...

1. go on with the date as planned,
2. cancel if he calls me one more time to "chat," or
3. if I go on the date, do I dress-down instead of dress-up, so maybe he'll find me uncaring and uninterested? 
4. if I go on the date, do I kiss him goodnight?  or is that inviting him to ask me out again?

If I cancel this date, my friends may never speak to me again; if I do go I may never speak to myself again.

I think I already answered my own question, but any help you can offer would be appreciated.  Thanks.
