Its simple ( well in my mind). Women are attracted to a guy that has a LIFE, has his sh1t together, knows what he wants, is popular and comfortable with himself.
If you dont feel comfortable with yourself, others will sense that around you and it rings alarm bells..I'm not saying this is true for you.
Also if you have a life, then that makes you LESS available anyhow, which women like. We all want whats not easy to get.
is it easy to get a ferrari? hell no.
is it easy to get a ford fiesta - hell yes, its a run of the mill car. nothing special. You should be aiming to be the ferrari my man.
Are you beggning to get it? spending too much time with a chick whenever she wants is not normal ( or at least in my life) - I have plans, I cant drop things just because she wants to hookup, no matter how fit she is.
Now maybe if she was hot and going to tie me to a bed and handcuff me, well maybe then...
oh, and dont be so firm with this women face to face, she will suddenly think you've changed and the friendship may end. you need to do it in a way to keep her hooked whilst you meet other folk, do other things.
SUBTLE changes remember..
Oh and yer as the guy above said, she is testing you by saying:
'she tells me there have been several times she's been attracted to me, i.e. she could have sex with me as far as she's concerned'
all i'd reply to this is: aww thats really cute. your lovely.
and leave it at that. dont go getting all deep and serious. Shes testing to see if your still interested in her, and yes she's playing you.
