Started doing approaches in the club on the dance floor(in Poland, if that matters). I usually grab a girl by her arm and start dancing with her, sometimes ask her name or where she is from, stuff like that.

They dance with me but the thing is that they are not very interested in me. They wont look me in the eye or dance intimately, everything is kinda platonic. If I dont bail myself they will come up with an excuse to leave.

What am I doing wrong? What should I improve? Thank you
