Self esteem

My self esteem has been so low💔 and yes you guessed it, it’s over a guy. I just feel like he finds every female more attractive. I feel like he makes them feel more beautiful and it hurts so much. Its tearing me apart. I don’t know what to do :( I feel so ugly and unsatisfied with myself. I just wanna feel important to someone. I wanna feel like someone’s first options 💔 I wanna be the most beautiful girl in the world to someone. Idk whst to do with myself anymore :(
