I really want to just go up to a girl and tell her she's cute... I see so many girls I want to do this to, but god damn it I can't get my feet to go.

I am comfortable with girls and can small talk, decent looks, been with a lot... but this stopping a girl and direct game seems so hard.

Anybody progressively get over this fear? What worked for you?

I even will get IOIs from girls and not stop, and beat myself up for being a dingus mcgoo.

Maybe start by going up and telling them they're cute with the clear intention of not talking to them after? "I have to go, but I need to tell you... you look adorable" and then not sticking around no matter what?

I did something similar before in college and it went pretty well. My buddy said "just have fun tonight, like a kid. If you kiss, get a number, or fuck a girl I'm going to be pissed at you. Just fucking have a blast tonight" and there were girls all fuckin over me.
