WTF

I am sooooo confused.

Don't know why the last post looks like it does. Everything was/is so nicely spaced and laid out in the dashboard. WTF is going on when it get published?!? Even looks right when I preview it, but then looks like a jumbled mess in the blog...............sigh...........IF there is someone out there that knows what I'm doing wrong, or even cares....please, please, please, tell me the secret.....Do I have to go into the "edit html" and manually enter the line breaks????? If so, how the hell do I do that?????
