The hot and cold coworker?

So I have the case of “how often do I interact with this coworker” happening.
It’s weird cause she acts like she doesn’t receive my work private messages (or maybe she is not lying and isn’t getting them) and then she one time goes “hey Hannah you work Monday right” wanting to know if I work Monday. She didn’t have a reason for asking that so I was confused. then at work today she talks about anything and everything and like really opens up. this happened a couple times at work and then we don’t talk between shifts. I don’t get why she talks to me like we have known each other for years at work and then ghost in between. she seems excited about doing something outside work and then she “forgets” to message me (if she’s lying and isn’t actually forgetting). She told me she has adhd and doesn’t get texts and respond to them as quickly and that many people kind of text her at once.

is this a “I need to fix something with my personality” thing cause this seems to happen with a lot of people and then I never hear from them again. Only reason I hear from her is cause we are coworkers.
