What the heck would you call this?!?

when he says to "have a good night my dear friend" it means he thinks of you as more than just a friend. you're his "dear" friend...if you know what i mean. he wants more than mere friendship, probably. but to find out if it's sex or a relationship that he wants from you you need to sit down and have a real talk with him. ask him straight up what he wants from you. it's all about communicating. you'll really never know until you talk to him. best of luck.
