Brought the passes on herself? No. You can flirt with someone, if they don't reciprocate, it's not cool. First move = kiss is not flirting, it's massively inappropriate.
Yep, she did. But that is not a blame on the victim.
If you wander round flirting with people they are going to make passes at you. She admits this, and seems fine with it. There is nothing wrong with wandering round being flirty, there is nothing wrong with guys taking that as a signal to make a pass at her.
Feeling her up after being rejected definitely is wrong.
Asking a woman if you can kiss her may feel hard, but looking back on my single teenage years, that's a whole lot easier than "going for a kiss".
I say all this like I'm Mr. Smooth. Nothing could have been further from the truth and I've been in a committed relationship for 13 years. Watching an episode of Freaks and Geeks last night just brought back a lot of tough memories prior to meeting her.
On the other hand, if you can pull off just going for it and she digs it, that makes you look really good.
Someone being flirtatious with others is not a green light for you to make a pass. Not if they're not flirting with you. Even then, there's still plenty of nuance and context which would determine whether that's acceptable.
In this case he was in the wrong all the way; but you could put down everything up to the kiss as misguided, or confused or as simply idiotic behaviour. Guys get funny around flirty girls and make stupid choices.
But action after the clear rebuff is a different matter (and this was sorta the point I was trying to make but it got a bit bogged down).
(on re-reading, in this case, I'd only excuse the bit up to the kiss in this case, he seems to have forced the kiss instead of just going for it [if that follows]).
But sometimes, the first real move in a relationship is a kiss, which comes fairly much out of the blue.
Context is everything.
