What happens that a girl always wants to hug you?

it depends. When some girls only hug you or they're around you a lot this could mean that they have a crush on you or they like you, but if shes hugging other guys she's saying that she might like you but there are other guys out there that she could date

If you like this girl back, ask her for a hug or talk to her often because you never know. it could always happen...
