Only he knows what he is hiding, I'm not a psychic. Yes a physical relationship, but that is all. He is not the one for you.
The fact that you are questioning what will happen to you, makes me think you and he don't know each other at all. He is a stranger to you. Its better if he comes to you instead, you will be more safe and on your own terms and you can take your friend with you then when you meet him. In a foreign country you are on your own, not good for a young girl.
He already was here 2 times for couple days and it was wonderful and perfect. I just wanted to know what to expect if i go there
