If you/your crush was moving away, would you confess?

if i had a crush and they moved away i wouldn't tell them. iv been hurt before like this and telling them makes it harder. because once they move and if you do try a relationship that will be even harder

I confessed over text after we graduated high school and had started college. It wasn't like I expected something, but just that I wanted to acknowledge that those feelings existed.

See I plan to hopefully leave the country next year. But there is a guy who I work with that I really like. I am sure he knows how I feel because everyone else at work knows and tease me about it. But I haven't told him personally. I don't want to regret not telling him, its just that I know he isn't interested and nothing is really going to happen. Recently we haven't been speaking as something happened on Halloween where I got fed up of him looking at other women and kind of stormed out of the bar. He tried to talk to me the next day but I didn't want to be rejected.

Still don't know if I should build up the courage and just tell him for the sake of getting it off my chest.
