He said to you -
You do know that this won't turn into anything serious, right? Realistically, you live too far. I'm not trying to do a long distance thing. This is just for fun.
Aside from bonking you over the head with your own tablet PC, how clear does he have to make things?
He told you -
- It is not serious
- It will not become serious
- You are too far away
- He is just having fun
He is trying to be nice to you and convince you that some pleasant Skype chatting (sexting, too? I don't know and I won't judge that) does not mean anything special to him.
The problem is, he is being far too nice, and you are attaching to his being nice like a remora.
