Eejit that is fantastic that you found your "one" and it sounds like you are really a guy that understands love.You care about making sure she is happy before you even think about yourself.
Make sure you never forget that or take her for granted,because I made that mistake and lost my "one" after 15 years together.I'm telling you it feels like someone ripped a big chunk out of my heart sometimes,so don't ever get complacent.Bring her flowers at random times,and keep showing her that you really love her all the time.
I hope you spend many years together,and may they all be joyful,happy,and full of great sex.
