Search Results: asking a girl out to lunch

I've been good friends with this girl throughout our 1st year of college, and we were always together at least 2 times a week. I asked her out about 7 weeks ago. She said yes and seemed pretty flattered. We were busy the first week, and second week she didn't answer my simple text asking when she was free that week. So I text her again a 3 days later how's it going, and she brought up going on a date and we made plans. Then we went on a dinner date and it was nice, but felt like we were just hangin out. B4 we parted she mentioned seeing a movie next. I hung out with her the next day in a group of people and that's the last time I saw her, 6 weeks ago. 3 days after that I asked if she wanted to see a movie that weekend and she didn't reply until the next day saying sorry I didn't write back I'm going to a basketball game Saturday. I asked how about Friday or Sunday and she said I'll let you know by Saturday night. Saturday night came and nothing. I figured it was her nicely saying no, and dropped the date thing. I still enjoy our friendship, so the next week I asked her if she wanted to go to the gym like we often do together, and she replied yeah I'll go! Then right before something came up. A couple days later she text me hey I see you, and we had a short convo b4 i asked done with class already? No reply. Yesturday, 3 weeks since I last text her, I sent a text hey do you want to grab lunch. She replied yeah let me shower real fast, I'll hurry. Of course, right before something came up and she couldn't. She apologized and said maybe we can get dinner. So 2 hours later I said we can get dinner at 7, no reply. I canceled plans thinking maybe I'd get dinner with her, and she replied at 7 sorry I had a soccer game. At this point I am kind of frustrated. I get she's really busy, but it almost feels like she's blowing me off. Plus it's kind of shitty she replied so late, I'm sure she knew she had a soccer game. Is it right for me to be frustrated or am i overreacting.
