I am no expert, but here's what I would have done differently:
- If I didn't feel that she was down for a kiss, I would have ended the interaction at its highest point (4 venues bit too much??) and would have waited for another date with the same girl in which I would have tried escalating again.
- saying 'i like you' directly (in a way which indicates you are down to fuck) is probably not a good idea (if you want sex). It takes all the fun factor away. girls love the feeling when they know they care more than the guy does. Reverse this, and the girl won't be so interested anymore.
- showing naked pics of someone you have slept with isn't a good idea for many reasons. I don't even know where to start.
- i would have joked about her accusation by saying "i
am taking advantage of you, and you love me for it" while smiling and winking. Qualifying ("I'm selfish") or going defensive ("I didn't mean to take advantage") aren't the best of strategies.
Of course Dragula may be right when he says you guys were not compatible, but we'd never be able to know whether that's right or wrong. In the end, you can only try to be at the best of your game.The rest is not in your hands.
Hope my analysis helps
