for example if they look like your type (personality based on their physical appearance)
Most Helpful Girl
You can crush on someone based on their appearance, but I'd say its a much more superficial crush than a crush on someone whose personality you know.
When you say they "look like your type (personality based on their physical appearance)", you're just projecting what you THINK or WANT that person to be like on them. It's not representative of who they actually are. You're just crushing on the person they are in your imagination.
I don't believe you can love someone without actually knowing them.
