He just want one night stand and already thought that you are easy.
I don't know the extend of you chat, if I guess.. it probably more than just friendly chatting. Most girl who serious with their boyfriends...don't lead any guy on to think that you are willing to do it with him. Just a thought about palnning to sleep with him the first day...not just a guy, I think you are easy.
If this is Thai guy..will you think about sleeping with him the first time you go out with him???? No wonder why many of American friends said that they were surprised about how easy it was to get laid for free in Thailand. I had to tell them that person they met were just some slut who sleep around a lot..decent and well brought-up thai girls are not that easy!!!
