I have recently started to approach girls more frequently. Not as much as I would like to and with not much success, but I am starting to realize when some girls "want" to opened and noticing some IOIs. However, my problem is not about approach anxiety, although I am not 100% free of it yet. My problem is that the more interested I realize the girl is, the more nervous I get.

For example, today I realized a girl was checking me out and I smiled. She shy smiled and looked away - IOI. But then I got nervous and walked right past her. Another example is with a friend of mine: I constantly flirt and tease with her, but if we are by ourselves and the opportunity crosses my mind, I just lose all ability to do things properly and do not escalate.

Was wondering if you had some suggestions to overcome this...
