I’ve been doing this for a couple months (now I have a girlfriend) and it has worked every time. When I am with a girl I am attracted to that I am friends with I use one line to take her for seeing me as a friend to seeing me as someone attractive. It goes:
“I am so happy we are just friends”
Yep, that’s it. This makes women think “why am I not good enough for him” and try to prove their worth. This has worked for my friends too. Try this and let us know how it goes.
