If a girl ignores my messages does that mean shes not interested in me?

Yes, it’s best for you to move on.  Continuously messaging her will only make things worse.  

Move on, forget her.

Are you absolutely 100% sure she got your messages?   IF she has not looked at them - COULD that mean the electrons did not line up and she never got them?

Consider using another feature on that hand held device - and call her.  Be cool and non-accusatory.... just be real and say you are following up to your last messages - not being sure she got them.  Ask her if she wants to go out again.

IF she say no, then you, well, know.   IF you go to Vmail and don't hear back after another week or so, then, well, you also know.  

For all you know right at this time... she MAY be sitting their wondering why you have not gotten back to HER. (?!?)   Wondering if you a ghosting her.  As great as all our current tech is - you have to realize that is it not perfect.

Hope this works out the way you want.  IF not - count your blessings.  Someone that is not strong enough to be straight up honest with you and hides behind tech is not someone worthy of your time.  Good luck.

Since you know her number, how about CALLING it instead of txting? That'll square things up some. Txting is the laziest way of communicating people have come up with. 

She ghosted you. When she met up with you she probably didn’t like you or have fun was just trying to be nice probably. Unlucky pal😂😂😂😂😂😂

Yea
