What's wrong with the formatting?

I've just realized that the formatting for my blog seems to be off, as in when I click to look back at the old posts, it's all in one long paragraph instead of how I typed it out... Help, Shen?

I thought of doing a review of Angus Steak House in Pavilion since I've got the photos and all with me but Im too tired. Got back at 3am last night. Was out with my cousin-in-law Allen (it was his birthday), cousin bro Leong Jr, Jenny, Kok Keong and of course Rommel.. Tonight was Prem's wedding reception so just got home and I want to sleep... *yawn*... Night..
