^You're not thinking of taking naked pictures of her
\ I was asking for some genuine advice rather than such lame stuff man.) and putting them up on her site, are you? Because that would be some surprise!
This thread gives me an idea of how to break up with a gal politely :
Step 1 : Register a domain with her name in it.
Step 2 : Paste some random ugly pictures of her inside a heart shaped e-balloon, preferably pink in color with glitters around it.
Step 3 : Write on the website in bold letters "10 things I hate about you" and "How not to treat your boyfriend" and so on.
Step 4 : Facebook her the link to her new website and put "SURPRISE!

" in the heading.
Step 5 : There is no step 5, you are free. If you are very lucky you won't even receive a hate call/message.
