Been texting this girl for a little bit and sometimes she just leaves the message on seen without responding. I asked multiple times and she says she just gets into an antisocial mood swing where she doesn’t text back. She’s been liking all my ig pics and I even see her in the gym and she always waves and smiles at me. Am I wasting my time trying with her? Because I find it hard to believe a girl won’t text back a guy she’s into.
