Incest crush on my brother

So recently I moved back in with my family after finishing up my bachelors degree and i'm currently bunking with my brother. He himself has been out in the open for a while, but i've never been interested. Being here for a while though, i'm starting to develop feelings for him by just spending time together. I know incest is wrong, but should I keep it as just a crush or should I tell him? Thanks in advanced, DM me if anything please!
