There is no doubt that his behaviour is very inappropriate towards the end,but according to your post he was interested in the beginning, you were skeptical. After a while you were interested, by then it looks like he moved on maybe. It looks like the relationship lacked proper communication. Once he suggested to meet for coffee, you took three weeks to reply,for some reason( you mentioned in your post).Did you communicate during this period about how you are planning your coffee date and when to him.I would be upset if someone is silent for three weeks after a mutual agreement on a date.I would tell the guy if I am busy or came down with flu or any other reason..of course I wouldn't behave like him ..In your original post,it looks like you made a lot of assumptions too.Sometimes it is better to express verbally rather than just assuming. Like when guy said when are you taking me to coffee, maybe he was expecting you to set up a date and place.Just I am putting my thoughts out there.Not blaming you or anything.
