Went out with a girl on a date to a museum. Having mixed feelings about her intentions. How to tell if things look promising?

Ok so about a month ago, my sister-in-law hooked me up with a friend of hers. Her friend (let's say Molly) was pretty cute, smart, good sense of humor, but shy. She also just broke it off with her boyfriend a month prior to the meet. So after the meet I suggested we meet up and get to know each other. She seemed enthusiastic about it and next thing you know we are at a museum, then out for a nice dinner.

Now I thought things went well, as I mentioned my family had a parrot, she asked when she could meet him and said she'd like to hang out again but her schedule was chaotic the following week. Later that week I tried to see if she was available the following week. She said she was busy, but sent a kind message about trying to stay warm as there was a hwat warnjng. Skip ahead two weeks later, I decided to give her a call. She said she was between jobs and probably won't be able to hangout for a few more weeks.

So my question to you is what ahould I do. Is this girl actually interested in hanging out? Fyi she did just break off a relationship and is actually looking for work after a busy summer, but I'm not really getting a direct answer here. Should I wait, or move on?
