advice ??

i recently met this guy , & i’m super attracted to him. we definitely vibe , & have a connection.. i’m starting to really like him & catch feelings, but i don’t want to confess how i feel then soon be disappointed if the feelings aren’t mutual. he would definitely flirt with me , but i believe he does that to everyone so i try not to feel special. he’s one of those guys that every girl wants, & can sometimes get cocky.. what should i do ?
