Text pasting vertically

Need some help here. When I copy text and paste it into illustrator it pastes vertically and in an extremely long line. I think it's pasting as an object because when I tried to shrink the box then the text shrinks as well. Also wanted to mention that I'm copying a paragraph and when I paste it it pastes only a sentence. Not sure why this is happening when my "paste without formatting" is off and this problem has never happened before until today.
