What was Bella from twilight's age when she got married?

Well, Renesmee and Jacob don't get married in Breaking Dawn, or in the new book... (the second life of Bree Tanner).

So, as far as the twilight readers know, they dont get married, so im afraid i cant tell you how old Bella would be,

but, i can tell you, that when Renesmee if an fully-grown half-vampire, half-human, Bella will still be 19, because she never changes her age, only her human dad; Charlie thinks she does, and Edward will still be 17, And Renesmee when she is fully grown, will be 15, only 2 years younger than her dad,

mad really. But i love Twilight.

I hoped i helped.
