Just won a short game by resignation against a 298 rated player,with me being 235 rated.

He lost 65 rating!? Why did he lose so much rating from this one match?

Because there are several components of rating change. One is the difference between the two players ratings. The second is a statistical measure of how accurate each rating is considered to be. New players typically have ratings that are not considered reliable. They can change a lot in one game. (Your opponent had never played blitz games before today.)
