and especially the WZA - some feedback/advice please.

I have been pursuing a girl for a while now. When I say that what I mean is that we went on a few dates earlier in the year but it fizzled out to nothing. She was very aloof and although I don't like gurlz who are too submissive, it became a real BORE.
ANYWAY - she has been back in contact recently - asking me what I've been up to etc. I got a bit excited cos a)she is super hot, b)I am punching WAY above my weight and c)She is quite a bit younger than me, which is good for the ego, natch.
Anyway 2 - I was cycling through town earlier and saw her taking coffee with some PUNK. When I say punk, I just mean another man.
What's my next move guys? - I want to get inside her, but she is a real player.She probably has quite a few gimps on the go at any one time, being super hot and skinny and shit. Shall I add myself to this miserable list or sever ties with immediate effect?
Thanks for reading my TRUE story
