I[21M] have developed a crush on my flatmate[20F] and am not sure how to ask if she’s feeling the same without making it awkward

I live with 3 of my closest friends in a shared apartment. Recently I’ve developed a huge crush on one of my flatmates. Normally I’d ask the person out but since she is a really close friend of mine and also live together with 2 other friends, I am worried if I talk to her about my feelings it will make the shared apartment life really awkward. I’m 100% sure that she doesn’t feel the same way. But my delusional mind still thinks it’s possible and sees “signs” in normal things. So in order for me to have closure and be able to move on and get back to being friends I need to hear it coming out of her mouth.

I’ve been doing some thinking and was planning on telling her in a few days. Once it’s out I can start moving on and hopefully in a week (of avoiding her) it will be over and can tell her that we can get back to normal.

My question is: Does anyone know how to handle this situation like a responsible mature adult? Through similar situations, experiences maybe? And if I do talk to her about my feelings is there hope for things to stop being awkward and get back to our normal lives?
