Feel like an idiot, because I should have known?

Well there is this girl I was talking to for a little bit. I mentioned we should hang out, and she thought it was a good idea. So I tried to set something up with her twice, but both times she cancelled (I said lets reschedule the first time she cancelled, the second time I didn't bother say anything). She mentioned that she felt bad about cancelling (she mentioned that both times). Since then I reached out to her and just spoke to her like normal. She answered and that was the last time we spoke. The crazy thing is that sometimes she would've texted me out of the blue to see how I was doing, how my day went, or just to say what's up. After the second time she cancelled she hasn't done any of that, so I just didn't text again since the last time I did. I just don't know what the heck happened. Now I feel like a fool for even trying, because I feel just said yeah, just because and was like I don't really like him let me back out. My thing is why not just be upfront and say look I am not interested that way, I don't think we should hang out. Now I am sitting here like bobo the fool, for even trying. What are some signs that a woman is truly interested? I just feel like I thought I knew, but after this it's clear that I don't. Thanks in advance
