Reason she would do that?

There was this bar that I used to hang out at. One night I'm chatting with a bartender who I had pretty much just met (saw her the week before but she was a waitress and didn't talk to her). An hour in she was like we should exchange contact information and all, we exchange numbers. Guy comes in later and says how I'm on instagram etc. She was like I'll follow you. He then asks her for her number, she says no, you have my insta you can message me there. She even texted me the next day. I thought this may be interest. It wasn't. No big deal, but I figured going back would be awkward and all so I obviously stopped messaging her and going to the bar. My guess is is that it was in a friendly way. Also unlike the other guy I wasn't going after her I was being nice and she knows I come by like a regular. It happens, a misunderstanding. Anyways, 8 months later, just recently, she texts me out of the blue. It was weird and I was acting weird, I was like who is this why are you texting me etc, she was like why not why are you being weird etc. Stopped texting. Whatever, I don't care. But my question is why text me 8 months after no contact. I barely knew her. I know some girls like attention but she refused to give the other guy her number and she is an attractive bartender who probably get s hit on numerous times everyday while working and I don't even go by. Could she maybe have tried to reach out to say forget about the past and no hard feelings and all and to come by sometime again. Like it seemed she just liked talking to me and all. The other people there liked me as well, so I figure at the very least I can go back to the bar and it won't be weird and all.
