Am I being unreasonable?

My boyfriend doesn't pay attention to me at all. I can literally see him online on every social media, he would rather talk to this other girl every single day and reply her but not even reply me or talk to me. He literally doesn't text me as much as he texts her and shuts me down when I initiate dirty talk. I'm to a point where I'm just tired of it. Idk if I'm being unreasonable when I say i deserve more attention than she does or than being ignored.
