Ok so i just let another hot broad that was obviously interested slip away again.. I always seem to settle for the "next time" even when i know my time is limited.. Im having a real hard time getting over this.. Im fairly good at getting a girl to laugh open up & keep the conversation goin, but when i get down to the get down i seem to not be able to verbalize the final words to get her to kiss..
ExamPle:

This weekend i was at a wedding out of state & had set up to meet & hang out with this hot girl i seen only like twice before.. She has a bf but showed up to the event by herself.. Right away i jumped on it had good convo & a few drinks.. Long story short her dad ends up getting in a fi ght with another dude & she reacts by running over & trying to get involved by hitting the other dude(shes a fighter). Throughout the commotion i followed & shoved the dude protected her afterwards & walked her outside & got a little close.. I can tell she was a little turned on by it, & when the commotion outside died down i walked her to her car reassured we were gettin together the next day & settled for her "yeah of course ill call u tomorrow morning." instead of mannIng up, comin up with something slick like walking behind her car out of view of others to kiss.. Seems like i can never think of the right move when im in the moment.. Please help with this if u have any advice.. Maybe some routines or anything that u think might help would be appreciated, thanks..

You have to break the seal by just doing it. Don't worry about rejection because that means it's time to use your time on other girls.
Manning up as you said is exactly what you need to do. Be a man and take the lead she will find that even more of a turn on. Trust yourself to get in there and get it done.

If that is still a struggle make a game out of it, play the 5 lies game with the result being a kiss or make some bets etc.

Yeah that 5 lies game seems like a great idea!!. But my problem is that final little nudge to get em to close.. Can u maybe give an examPle of doin this with a close at the end.. Sometimes i can feel the attraction but theres that last step that always kills it for me. I can get em to isolate but i guess that last step is not exactly the something slick to say, its more of just doin it & goin in for it..

Exactly if you have put in the ground work you just have to get over and go for it, the worst that happens is she pulls away and you go on to sarge other girls.
