what should i do?

so i met this boy freshman year, let’s call him josh. josh and i started dating around mid January and broke up march. i was so heartbroken and i never got over him. in sophomore year, we became really close and started talking again during Christmas. we talked all the time, flirted with each other, he drove me home, and face-timed for hours.

one day we hung out and we were basically all over each other. that week we started talking about getting back together again. after all it’s been a year. he told me that he liked me, but he also likes this other girl. we went to this party, and afterwards he hung out with the other girl. that was friday. it’s almost been a week and he likes her more than me.

we’ve been talking for 3 months and he completely left me in the dark. now he talks to the other girl way more. what should i do??!

p.s. i’ve literally been in love with this guy for more than a year, i really want him back.
