The signs that a shy girl has lost intrest of you is when she starts to not hang around you anymore or that much or when she is not talking to you or about you to anyone.
IF YOU WANT THIS GIRL TO REKINDLE HER INTEREST FOR YOU WHAT YOU HAVE TO DO IS VERY SIMPLE. JUST IGNORE HER AND LET HER SEE YOU BE HAPPY WITH ANOTHER GIRL AND BELIEVE ME SHE WILL REGAIN THAT...
the boy sign is a circle and an arrow pointing up and diagonal, while the girls sign points down diagonal with an arrow but its more cross-like. hope this helped!! :]
it depends on how you ignored her say if you were going on a date and you just didn't show up then I'm pretty sure anyone would be ticked off. but if you don't respond to her text or something small...
