You are def right about the whole happiness like that doesn't last thing...they always ruin it somehow!
I know Chadam is a huge fav right now, but I still just am not feeling the spark that I once felt for Shadam. I don't truly know if I want them back together either though, so I wasn't really caring one way or another. She's a great actress & I do enjoy her character, so I'd hate to see her go before she really gets going, but I fear you are very right. If it isn't death, it's gonna be something pretty major to shake them up.
