<human>: Can you give me a shortened version of the text?

I'm new into a relationship of one month's standing now with my girlfriend.  Everything's brilliant, and I couldn't be happier.  However, my female colleague, who at 20 years old and being far out of my age range, suddenly changed her behaviour toward me.

Last time I saw her, she kept on blowing down the back of my neck and tickling the same spot.  Suffice as to say, that's girlfriend territory as far as I'm concerned.  And then yesterday, she noticed a silver ring I have on my hand, and just reaches over and grabs my hand without so much as a by-your-leave, apparently in an effort to compliment me.  

I sharply reprimanded the unwanted invasion of my personal space, but she's still trying to find every excuse to flick her hair at me, make googly eyes at me and generally be a complete and utter pest.  Finally, and most importantly, I know for a fact she has a boyfriend.  I just want her to bugger off without mucking up the professional relationship.
<bot>: Work colleague with a boyfriend suddenly starts flirting when she finds out I have a girlfriend and I want the colleague to sod off.
