In Google Docs, if you go into 'Line & paragraph spacing', there's an option called 'add space after paragraph'. In Microsoft Word, you can go into 'More Paragraph Options', then into 'Line Spacing' to turn spaces after paragraphs on (if it isn't already!). You won't actually be leaving spaces between paragraphs, but the software will make it look like you are.

If you use a different writing software and it doesn't have that kind of formatting available or you can't find where to change it, that's fine! It's easier on me if it doesn't spaces between paragraphs, but it's not the end of the world if I have to comb through your fic and reformat it a bit.
