Loving someone 'quietly' isn't always the way tho - perhaps you assume she knows you love her, but not all women CAN assume. Relationships need working at constantly. Think of it like feeding yourself - you dont think 'ah i've eaten, that will last me the rest of my life' - you need to eat again when you next feel hungry - and so it is with relationships - you have to feed them, positively. It sounds to me like she needs a few words of kindness/love. something deep, from your heart eg. 'you mean everything to me' or 'i would never change my life with you, you are special' but make it sound as tho you mean it. Men do tend to see love through their partners actions but women often need the words too. I would say you're half way there with the chocolates and flowers, she needs that little extra bit from YOU, from deep down. It doesn't hurt to do that now does it? Even if, as you say, you're not like that - just make the special effort. People dont always have the same needs as they always did, it's part of growth, love and understanding. Give it a try, for the sake of you, your wife and your marraige, if you treasure them.
