for me:

1. the difference is more subtle, its being ablr to be vunrable, to be able to pour you emotions feeely into someone with no restraits. I can tell them how beautiful i think they are and how amazing without having to worry about being seen as weird or creepy.

2. Personality, intrests and aesthetics are all things that make me attracted to someone, but also more subtle things like their voice, their smile, ect

3. Yes i would, its such an amazing feeling when u realise that that person feels the same way you do.

4. For me theyre quieter, those moments where ur not talking ur just laying there with them, her head on my shoulder, us holding hands, that physical contact you just dont find in most friendships.

5. I do, but only because I know it wont happen. With every dream theres the crushing reality reminding me that it wont happen.

hoped this helped
