Are these valid reasons to end a relationship?

Yeah, I'd say you did the right thing. Think about it: it's early in the relationship-- a time when he should be eager to spend time with you, eager to make an impression and eager to please you. This guy's not eager to do anything but what HE feels like doing at any given time. That means he's either not all that into you, or he's just a selfish putz. Either way, it's only going to get worse. Finds someone who makes the effort. That's the least you should be able to expect.
