I've been gaming over text for quite some time with multiple girls. all that's missing is the last step. they play along and everything i keep my frame. tease. they tell me how much they like it. blah blah. asked for a date excuses came up on the day of the date. happened once. twice. THIRD. and that's a strike (Time for some Red Pill mentorism)

they're fairly into me. answer what ever i ask for. (pictures, numbers, intimate information)

most of the girls are young (17, 18) i'm 20.

their excuses are fairly believable. i called BS on every single on of 'em. stopped talking for three, four days then started again.

what should i do? what mindset should i use? and to my main question: how to push to that last step? (obviously by dating them but how to convince/reach that last step?)

Edit: let me elaborate on "being into me", they got jealous whenever they saw a new picture of me with a girl or whenever one of the girls checked in on facebook. start asking me about the girl and why i'm with her, try to convince me to leave. sometimes they try to hide their interest but to me it's kinda obvious (Thanks to TRP)
