So this guy I've known for 3 years we both really like each other and when someone at the pub asked him why he was down this way (we live 5hrs apart) he said visiting the girl(me) and he talks about us having a future things together but when I want to make things official bf gf he doesn't answer really he says I don't see a problem in the future

What does he mean?

Does he want me to be his gf?

What do I do?
