mashallah...:).
What type of sparks are we talking about? Like when your husband looks at you and you feel butterflies in your tummy and things like that?????
no butterflies ones is intial stage. later the sensation changes but takes other forms. i remember in our early marriage the min we were alone or he even just sat close by my heart would beat really fast and he will actually be hot as if he's having a fever. it doesn't happen like that any more but the spark is still there.
