Do I HAVE to change my name?

i've tried to search for relevant topics on this already...but i can't find any.  i've found tons of information on this site if i WANT to change my last name (i just got married last december)....but i have no intention of changing it on anything (passport, visa, credit cards, etc.), nor do i want to.  maybe it's a stupid question, but do i HAVE to change it? or even hyphenate it?  can anyone foresee any problems in me not changing it? 

You don't have to do a thing if you don't want to change your name.  And, if you change your mind next week, next year, or even next decade, it's not too late.

oh good.  that's what i was thinking.  well then, no worries for me.  thanks!

yup--- no need to worry , you don't have to change a thing.
