I think I'm in love and idk what to do

There's a girl I like I've known her for at least 3 years now unfortunately I've caught feelings (not too thrilled about that) she makes me feel safe and heard she's the most nicest human I've met in a long time

My heart tells me to tell her how I feel but my head is constantly reminding me that it would never work

We are polar opposites she's Verry reserved and quiet meanwhile once you get to know me I'm loud and talk alot

I always give her a text message every now and then and she will reply but then randomly the conversation ends as fast as it began like I know she don't do that on purpose but like in my mind I'm pretty sure relationships are meant to be about conversation and understanding and if we have trouble communicating as friends I don't think it'll work out in a relationship (if she even wants me)

And it really hurts cause I love her so much but there's just so many reasons aside from that one that proove it could never work

Like do I just live in delusions and never tell her how I feel?
