how to come to terms with being a "low value male"?

I have been working hard towards becoming the "main character" but it just isn't working out for me. I keep getting rejected by literally every girl even ones i dont think have soo much going for them tbh. So today my crush rejected me and Im ready to throw in the towel. im 31 and never had a gf. I make 6 figs and am in shape. Cant say it has helped with women at all :/. There's not significantly more self improvement I can do at this point. Im just capped at being a boring side character. Totally not my fantasy or what I want in life so im at a loss at what to do and how to accept this.
