Depending on the circumstances. I always believe you should fight for love, but when you try persistently and you still can't change a person's mind about you, it is best to give up just so both parties don't get hurt.
(I'm not a love expert, sorry if my advice isn't the best.) ╥﹏╥
"You choose me or you lose me."
Can't force your feelings onto something and if he knew how you felt for 2-3 yes and the relationship hasn't progress then he is not interested in you, so you better move on
Maybe this isn't the right place but,
should you give up when someone doesn't love you or fight for their love?
He is single but still can't move on from his ex, also we've been bestfriends for 5-6 years, he knew my feelings since 2-3 years ago.
