I feel like I need to confess my crush on a girl, whomst I'm pretty sure doesn't like me that much at all in order to move on, should I?

She seems interested in some converstions with me, we hung out for a quick smoke once. Known her from school for 2 years.

She seems interested in some text conversations, but is also uninterested at times.

I just feel like I cannot move on without telling her how I feel first, even though I know she doesn't like me back (or at least I'm pretty sure about it)

Should I confess? And if so, how would I go about it?
