You already know that his culture is different, so 4 dates isn't a lot! You're expecting too much too soon I think. He obviously likes you, he's making plans for the summer with you.......so be patient. I don't understand why you're worried about his "goals" so soon. You're enjoying his company, he's obviously enjoying yours, so why can't you just ENJOY without analyzing? He said he's not looking for something serious, so accept that......and of course NO ONE looks for something serious until they find someone they want to be serious WITH. You're just getting to know each other, just enjoy his company and give it time to develop! Relax and enjoy the ride!
A friend brought it to my attention that it may not be appropriate for me to date other men past a handful of dates. At first I disagreed with this and figured he would tell me when he wants to be exclusive. BUT, then again, exclusivity in dating is probably our cultural norm (I think) and I'm not sure what his expectations are. I'm now thinking along these lines because he is planning dates in the coming months and I want to be considerate to this great guy.
