You think about them a lot
You look forward to seeing or hearing from them
You notice small details about them
You want to talk to them even when you do not have to
You feel nervous or excited around them
You care what they think of you
You find excuses to spend time with them
You smile more when they are around
You miss them when they are not there
You get jealous when they pay attention to someone else
You want to know more about their life
You remember things they said
You feel happy after interacting with them
You imagine doing things together
You feel attracted to them emotionally or physically
You make extra effort to look good around them
You get butterflies when they message or approach you
You prioritize them over other people sometimes
