Search Results: excuses to start a conversation

I've been talking to this for about four weeks and now I'm not really sure what she's thinking or what I should do from here. Let me try and explain all that's happened so far. This may be a bit lengthy.

So about four weeks ago, I started talking to this girl on Facebook. She's a little shy so I figured it would be appropriate. We hit it off pretty well and found out we had a lot of common interests. We went on for about two weeks just having casual conversations and on Sunday we ended up hanging out. We had a great time and she texted me immediately after we split up that day to tell me that she liked that I was so tall and that she had a good time that day. The next day she texted me first thing in the morning and we had a nice conversation that day. She also told me later that night that she was really tired but didn't want to go to sleep because she wanted to talk to me. She texted me in the morning again the next day and we decided to hang out again the following weekend. No morning text the next day but I decided to step it up a bit and send her a nice, lengthy and creative text saying pretty much everything I liked about her and that I thought she was really cute. She seemed really happy to hear it but didn't really say anything back. The next day we texted some more but with no morning text again. The next day I didn't really hear anything from her all day. The day after though, I got another morning text and we talked all day, although after I asked her if we were still going to hang out the next day, she warned me she may not be able to, but gave a pretty legit excuse and suggested Monday instead. Monday, the next day she flaked again and said she couldn't, after I asked her also. Yet, again she gave a pretty legit excuse. I can't help but fell she's losing interest in me for whatever reason.

I'll take any thoughts you guys have about how it seems she's feeling and/or pick one of the options on what I should do in the poll.
