She asks me to hang out with her on Monday night. She then cancels and comes up with what I thought was a legitimate excuse. I stll think she is interested because she says to me; I'm so sorry, how about tomorrow night, same time? The next day she does it again and says I know you are going to think I'm a flake but my mom is not feeling well (she just got out of hospital) and I have to run errands and be with them tonight. I say somethiing like "No worries, maybe we can hang out some other time, just let me know". She never wrote anything to me after that, so we left it at that. I have a feeling she's not interested. Should I just delete her number?
