Why does this girl in my friendship group seem to dislike me for no reason?

I’m in this friendship group it’s me and this other girl. I have noticed that of the girls in the friendship group always likes and supports my other o friends posts, but she never ever likes anything I post. I see that she is always active and online and she is always reacting to the other girls post with a love heart but she ignores mine. I know she sees mine too because she views all my stories I post. She also makes comments about what I post in person like “I keep seeing you going out on nights out and I don’t know how you manage to do that and function at work the next day. I couldn’t do that” except the other girl in the friendship group posts night out photos and she has no issue liking her photos and supporting her, and commenting nice things on her photos. When I meet up with both girls the girl who never supports me makes comments that we never speak or arrange to meet up, but in the past I have tried making effort with her to meet but she always refuses and then ends up meeting up with the other girl in secret. She can never like anything I ever post on social media, but with the other girl she will heart all her instagram posts and comment “gorgeous girl” but ignore mine. Once she liked one of my pictures by accident but it was an old picture because she’d been scrolling back on my instagram and accidentally liked an old pic. When I posted a birthday picture of me she said “happy birthday I love your pic you look beautiful” but completely ignored it and didn’t like it

When I meet up with both girls for drinks or coffee, she will act like my mere presence bothers her. One time I met both girls for a pizza and I took a picture of my pizza with a flash on my camera and she kept saying “the flash on your phone has ruined my picture”, and then when the other girl went to the loo and it was just the two of us she was not making any effort with me and acted disinterested in having a conversation with me.

why does she seem to dislike me for no reason?
