reminds me of a situation i was in a couple of month back.
A girl gave me the ljbf text, she was used to us texting all the time so me freezing her out bugged her, she text me that night apologizing saying she regretted it, i told her 'i'm fine just dont message me for a while

' which resulted in her ringing her mate crying down the phone.
she text me again the next day asking if i was in a mood with her, i said 'no i never was i'm just bored of this cycle we are in, if your next message isn't something along the lines of can we meet then dont bother sending it i'm just gonna ignore it'
That night i was pulling her lil knickers down and she's now my gf who seems big time into me
my point is if she says she doesn't want a relationship then act like your not arsed and freeze her out, if she likes you she'll come back and thats when you tell her to either sort it out or leave you alone
