But I think it is weird to use the term "girlfriend" for someone you have never met.It's a case of semantics, honestly. Using the term is believing you've earned the right to use the term along with everyone else who uses the term, ie. people with relationships. It's that big social pressure to be someone who is in a relationship.
A different word is needed IMO. Maybe I am just old lolWell there's the adjective "online". I think that'd cover it.
