well like i said. its all up to you. I'm sorry your not having as much fun as you used to. But there's nothing stopping you from coming back for the next expansion and what not. try new things while your away. I was like you and want's having much fun after a while and just let my sub run out and did other stuff until I felt like coming back.

While I'm sure your fc friends will miss you I'm also sure they'll understand. if you have any reservations or feel obligated to anyone just remember its just a game. your biggest obligation in life is for you to be happy with who you are. and a game doesn't define that.
