Falling For Him

He broke my heart years ago. I couldn't just automatically forgive him for that. He was my best friend, someone I thought who would always be there for me.

Now that he's living here with me for the next six months, I don't know what to do. He's changed.

Should I just forget the past and mend our friendship?

Or what if he's really not the same guy anymore and it sparks up something else?
