Anyone else relate 😔

Has anyone else ever felt like your best friend would rather her crush ( who doesn’t treat her well at all but she is obsessed with him. Long story short) over you? Like I feel so stupid saying this but our whole friendship is based on me supporting and listening to how bad he treats her and how much she loves him and like I just feel as though I’m sort of just a shoulder for her to cry on instead of her best friend like she is mine. Not sure if this sounds petty and stupid but it’s honestly just how I feel 😔🤷🏻‍♀️
