Went on a date with a girl that went very well. We agreed to go on a second date but since then she's flaked on me a few times. Once to do an assignment, once because she was ill (I was sick that week too) and third because she had to work to cover her sick colleague.

She's responsive and apologetic about it and said she likes me, although I am concerned she is trying to string me along for validation. I've been talking to other girls so should I just let this one go? It probably sounds like oneitis to you guys but I felt like such a good date shouldn't go to waste without at least a follow up.
