A question on formatting in comments

When I make a comment on a post, no matter how I type it up, it always just shows up as one paragraph.

Is there something that I am doing wrong?

1: now I'm also wondering what it does to a post so... 2: I'm splitting up this sentence like it was bullet points

Edit: Spacing seems to be the difference, but I still feel like I shouldn't have to skip lines to start new lines.
