Ok so I was seeing this girl for about a month. Two weeks ago she asked me to be her boyfriend. Everything has been going great. We have both been taking initiative. Anyways today I text her something flirty in the morning. It took her three hours to get back to me. Her dad and sister complain about her taking a while to text back so I figured it's no big deal.
Anyways the last text she sent me was "Would it be cool if we hung out after dinner? My dad needs 'girl advice'

(her dad was telling us about how he was going to dump his girlfriend).
I sent back "Ah girls are always trouble. What time are you thinking? I can't be up all night again!

.
She has since gotten off work and would have had lots of time to text me during her commute from work to her dad's place. Should I call her and confront or just wait it out. It's incredibly frustrating as I know for a fact that she has seen it. Thanks for the help!
UPDATE: She just texted me: "we just finished dinner, I'll call you soon!

"
It's not too late by any means for her to come over. But I don't see how she couldn't have seen that text and then gotten back to me. I'm thinking maybe I should arrange other plans and then let her know "oops. You didn't get back to me so I went ahead and planned a jam night with the boys. Plans tomorrow?" As a way of letting her know I'm not on her beck and call if she doesn't bother getting back to me. Am I over reacting or is she playing games? Thanks again!
UPDATE 2: I called her back after waiting for a bit
Her: "Hey I'm just taking my dog for a walk can I call you in a bit?"
Me: "I'm just going to go hang out with Sam. We'll figure something out."
Her "Ok bye." (I hang up before she can finish bye)
UPDATE 3: Immediately after I hang up I get this text: "I'm sorry

My reply: It's pretty rude. Your lucky I'm hard to phase. I guess you owe me an explanation when you get a chance. I hope your dad is doing alright.
Hopefully she calls me and I guess we will see what happens from there. Do you think I made the right move?
