I'll be honest, your story is hard to follow, is English your first language?
Anyway, you make it sound like going to his house was going to be your first date. I think you should date someone a little bit before you "go to their house"
Then it sounds as if you said you WOULD come over to his house on Monday but than just backed out. If you did that than I suppose that is a reason to by annoyed, especially if nothing believable came up to interfere with those plans.
To just suddenly need to cancel to go to "uni" sounds like a lie and an excuse and that he's wasting his time trying to pursue you because you are the type who isn't interested but won't just say it, but rather, commit because you are scared to say no then you disappear and come up with excuses later.
I'd just move on and not pursue you. Also, I wouldn't advise going to men's houses unless you've been dating them a bit first.
