What does it mean when a guy chat to a girl and calling her everyday?
He is a korean guy by the way and I live in another country,we never met before ,and he call me sweetie,dear,lovely,he is smart really nice guy,do you think he love me or what?

I'm planning to visit south korea next year and I told him that

He also has a great voice and record couple of songs in a studio and he send them to me to listen ,and also send live song via email while we 're chatting,most of them romantic like "only hope-mandy moore","hello-liionel riichie"
And last time we talk on the phone he said next time I'll sing live to you on the phone,

So is that a good friendship or love?

Before you go over there my advice talk to him about what's in your mind
You can never know what another person is thinking.
And assumptions always leads to massive pain.

Talk to him about your feelings towards him

You have not actually met him. Personally I would say a good friendship is developing. If it goes beyond that you just never know. Communication with people are so different now. Many people end up eventually meeting somebody they will want to see, over the internet. Different cultures , etc. can have an impact. Only way to know how he feels is by chatting with him.

Friends, love is more than just songs, or fantasy thinking, or smitten feelings.

Neither, it is an internet friendship, so regardless of what it might seem like, until you meet the person, you will never know in what way he looks at you.

You won't really know until its face to face.

Not on the screen.

That's how people used to get together.
