getting over someone..

...i never dated.

now, let me explain.

this guy is the only person ive been interested in since my ex and i broke up. we became really good friends, calling each other every night and falling asleep on video calls at 4am. we had chemistry and we hooked up. we called it being each others rebound (he also broke up with someone).

turns out we both caught feelings but were afraid of telling the other person, because we didnt want to ruin what we had.

well, his feelings vanished and now he likes someone else. not the case with me.

i need help. people with periods (bc we are NOT excluding any gender in 2019), what is your advice on getting over someone you never truly dated?
