grats bro. hope u guys be happy forever.
but seriously NEVER think she will be a burden...coz if u think that way, one day this topic will appear during ur argument with her....then it WILL be very very ugly..

coz if she really loves u back, she will try her best not to be ur burden and help u back in life....a real relationship is about give n take continuously, no such thing as "i did more than him/her....so wad have she/he done for me??"
