Losing that spark for him?

well first of all you should work on YOURSELF and your marriage before you start criticizing him. tellin him he needs to get healthy clearly shows your focusing on his physical aspect and blamin your LOST SPARK FOR HIm is cuz of your physical attraction. work on why you guys argue and WHAT you could do to encourage him to loose the weight not tell him that he needs to get in better shape. maybe even workout wiht him, make it a daily routine so that you both can be healthy togehter. but remember if he starts lookin hot and fit WHOS sayin that ur spark for him will reapear.. it might be more emotionally and inner than that.
