So here is the deal, I asked a girl out from work who I've known liked me for a long time. (The reason I asked now was because I was ready for a relationship)

Anyway, first date went really well, we went and saw a movie and had dinner after.

So we planned to meet for lunch like a week later, we planned Sunday but then she said she had to go to her brothers soccer game. (she said before she doesn't get along with her brother before) so then we scheduled for Monday. So I ring her Sunday evening and some guy answers the phone and says she is driving and he said he'll get her to ring me back. :/

She texts me back and says something important came up with her mom. Then we re-scheduled to go to an expo next Sunday. (at this point i'm pretty sure everything is a load of bullshit and she is not interested)

So I text her about 3 days before Sunday and ask if she is still interested in going to that expo. She texts me back the day before and says she had been fighting with her parents and was in a really bad mood, also work called her in and said you have to work (she is casual btw). So then she offers to shout me dinner next Sunday. (This is the part where I'm confused)

Ok so It's Friday right now, I've sent her a text yesterday at around 7pm asking what time she wants to be picked up and she hasn't responded. That is another thing, she takes a long time to respond to text messages.

So what is the chance she will flake again, I'm sure it's pretty obvious what the outcome/signs are if she was to flake again. I'm aware of the possibility that she is trying to string me along, but I'm not going to burn any bridges just yet. So what advice would you guys give? I would really appreciate outside opinions on this.
