Is it so important to live together before getting married?

For me, I intend to marry the love of my heart over the next year. The dilemma now is whether to live together, spend money on rent and put our relationship to the test?

We sleep together, in my apartment or hers, sharing almost everything. I do not think living together with her will discover new things about her I did not know before.

But nowadays I’m told many like to live together before. Is it really necessary? Maybe I’m conservative but I do not think so and maybe I’m wrong on this issue.

Did you stop loving someone after living tohether?
