I might be misunderstanding the IOI given out by womens. As I have more confidence now than ever before, I usually find myself thinking a woman is flirting with me when in reality she is not. Maybe it's a problem of lack of experience but I don't know for sure yet.

More specifically, one week ago, I was asked by a girl to go to her roomate birthday, celebrated in her house. Once there we talked almost all the time, with a bit of light kino (touching my arms from time to time) and fluid conversation, we were almost doing body contact all the time. Then, all of a sudden she tells me she had a boyfriends that she loves above everything (it seems this is true).

Keeping it short,,, when a IOI is really a IOI and not normal interaction without second intentions?

EDIT: grammar

Thanks
