My Search For the One

I'm 34 years old and been married twice and never really had that .......CAN'T LIVE WITHOUT HIM feeling.  You know the one I'm talking about.. you get excited when he walks in the room, he is all you think about even 10 years down the road.  I would love to find the the love like my grandmother and grandfather did.  They were married for over 30 years when he passed away and up until her death 8 years ago she talked about him like he was still there.  Telling everyone how they met and her eyes would just light up.  I guess I'm just looking for that one that makes me do that.  The one that when someone asks me why I am the way I am I can honestly say it because of the love of a good man.  And visa versa.  I want to be able to be that person for him also.  Is that crazy to want that? Am I asking too much?
