So I knew this girl since middle school, we didn’t talk much until high school. Shortly after graduation, I would ask her out and managed to take her to the movies. After I got into a university out of the US we stopped talking to each other. When I came back for the holidays I’d message her asking if we can link up, to which she would reject me saying she is busy, but I would see her on her friend’s snapchat twerking on a guy. Forgot to mention, I graduated in 2018 so I was asking her out during the winter and summer breaks from 2019 to 2021. Eventually I took the hint, and stopped asking her out. A few years later in 2023 I posted myself catching a flight on IG, she then messages saying we should catch up, I ignored her cause I was leaving. Flashforward 1 year later, she suddenly messages me on Snapchat telling me she misses me, hoping l'm doing well in life. I message back asking her how she's been. After a while she says something I felt was of slight inconvenience and sounded a bit fake, so I leave her on read. She typed after an hr of ignoring her but then stopped. My gut feeling told me she didn't really miss me, but missed the attention I used to give. My question is am I overdoing it? I just think she didn’t really care for me at all.
