She can sell the marriage to her father that way.
She gets to do her job and be noble 90% of the time without Tormund there to distract her.
That same 90% of the time, Tormund gets to hang out with Jon North of the wall and hunt ice spiders and pine after Brienne.
It's just one month a year, Tormund and Brienne get to be together and poor Podrick has to push Bran around in his chair to meetings instead.
It's a win win marriage for them.
