I was interested in this girl in my social circle. Last time we hung out I had my arm around her and she was giving all positive IOIs. During spin the bottle someone asked if I would fuck her and I said yes and she seemed happy about that. When we hung out today her friends were telling me to kiss her on the cheek. We sat on the couch and I put my arm around her shoulder she leaned in closer. I put my hand on her leg and she put her hand on my hand. She would reciprocate handhlldinf and physicality. Then she says that she had a boyfriend. She had never merioned this before a d because of all the positive IOIs I was getting I thought it was a shit test. But it turns out she actually has a boyfriend and was just leading me on even though I was super clear with my intentions. It's fucked because I'm painted as the one in the wrong when she lead me on by clearly reciprocating physicality and being invested when she had a boyfriend and then when she could sense I wanted to fuck she got cold feet.

My question is how do I spot this sooner? Her friends encouraged me to kiss her and but my arm around her and stuff. She didn't say she had a boyfriend until things got more physical. Dis she just lead me on over the whole night to get atte tion and validation? I could have spent the night gaming another girl in my social circle who I could have pulled.
