i’m really confused help me out here…

I was getting food at a wingstop and this girl (worker) asked for my number, she gave me it, i texted her “hi” later on. She told me shes been seeing me come in for a while and thought I was a mystery. Long story short we texted a lot about what we wanted in a relationship and was cool i guess, also talked about how many people we’ve been with (we both talked to the same amount of people) but i was just entertaining it just to see what happens. One day we both went to the same exact place but we didn’t know we were both there and so we met up there for the first time not at a wingstop just to say hi to see how vibes were. It was okay but she didn’t really seem to excited to see me

Later that night I got home already and she told me she just dropped her friends off at home and I tell her to pick me up as a joke and then she calls me after i said that, she said “do you want me to come over so we can talk in the car” i said “sure why not” (it was about 12AM at night)

Long story short we talked about bullshit, my life, her life, it seemed cool vibes and then we madeout, left at about 2AM it seemed like she really liked me and stuff we talked and kissed a lot that night.

she texts me a lot, she tells me “goodnight” and “goodmorning” and things about her day and whatnot, 1 day later… she told me shes getting sick and applying for jobs because she didn’t wanna work at food places anymore, but i have no idea if she was lying because i saw her car at work but only works 3 days of the week so i didn’t think she would use PTO (Paid Time Off) but i didn’t go in to tell her anything because i’m shy i guess.

she starts ghosting me and then she blocks me out of nowhere it was weird. I kinda liked her a lot. Do you have any idea why this would happen? Im thinking because shes kinda young and doesn’t know what she wanted, maybe she just got bored of me lol idk but thats that.

FYI she was 18, i was 21.
