creating a blog

Hi I am creating a blog for the first time and have hit a snag. I have everything working the way I want except that the text is like a run on paragraph. Unless I use html code inside the text field then it obviously doesn't display the paragraphs separately. Using html isnt a problem for me but I am trying to learn to make things for people who don't know html. So the question is....what does it take to get the page to at least display the line breaks between paragraphs when the user simply hits enter when entering the blog text.

Thanks!
