Girls keep using me as their wlw experiment

I (22f) am a fem4fem bisexual and I’ve been with both women and men romantically and sexually. I am not shy about my sexuality and have a preference for women and more feminine presenting people as well, but I keep running into this problem where women who have never been with women before will pretend like they want to be in a relationship with me just to turn around and realize they aren’t actually attracted to girls and just saw me as more of a friend. This has happened twice in a row now and has left me absolutely devastated both times. I’m just so sick and tired of this shit and needed to get this off my chest.
