Newest Question: She’s always late and now, not responding. What should i do?

So I had a couple dates with this one woman I really like. The first time we hung out, she was thirty minutes late. Second date, she showed up an hour and a half late. I was a little flustered but I dealt with it. I took her to Santa Barbra and to a nice Italian restaurant. I had so much fun w/her and we spent the entire day together. Third date, she is SIX HOURS late. We were supposed to get together at noon. Her excuse: family obligations. I didn’t sit and wait for her. I actually cleaned my entire apartment, went to get food, bathed and cleaned my cat, cleaned my car, etc. She showed up at 6:15 stayed for 10minutes and had to leave because she had to be at a sorority meeting. During those 10minutes, I told her off (in a calm, nice way), telling her that I was upset and she needed to update me, either that or cancel/reschedule. She looked cute sad, but she looked kind of mad with her hands on her hips all defensive like. I asked her if she had any input or opinion she said “No you’re right.” I told her my pet peeve is flakiness. She responded “Oh then you probably won’t like me then. Things come up, with my family and stuff..so yeah.” It’s been a day and i thought about it. Maybe I should give her another chance, I said to myself. I called her two and a half hours ago. Left her a voicemail. No response. Not even a text. I’m cute . What should I do now? I wanted this to work and I treated her well w/kindness..why is she being like this?
