There's a meme I saw a while back that I can't find again. A relatively pretty girl asks the same question up top and on the bottom a guy holds his head and says he'd date a tree if it approached him first. Absolutely tell him u like him, although make sure he's interested in you first.
If girls made the first move I can bet that guys would make the second one if they felt as though it was going both ways. As it would break the stereotype that the girl is needy. What would replace that would be like damn that girl is brave. I might actually try to keep this relationship and not let it pass by.
it's super fine, i'm always nervous when it comes to love, sometimes my self esteem gets low and i just don't see how or why anyone would date me, so knowing that someone likes me back really helps sometimes.
