WordPress with more than one comments section displayed, posts comments to all p

So, I’m building a WordPress page that displays a list of posts with their comments. At the bottom of each comments section, is the standard field for letting someone post their comment (like facebook). But every time someone posts a comment, it posts that comment to ALL of the posts on that page. How do I get it to only post the comment to that one post that you’re trying to comment on?

Also, I’ve noticed as soon as I post the comment, it sends me to a page for that post by itself, instead of returning to the list of posts with comments. Anyway to change that behaviour, too?

Here is my comments.php file in my template, i think the problems in here, but I haven’t found it yet:
