Im inside the temple of mara right now with serana to see if she has any weird side effects from being inside the temple and as of yet nothing has happened and she hasn't said anything
When she says she can't stand being in a temple and thats why she can't marry you is because she was [censor] in one by Molag Bal and it made her hate them ever since.

Also what would be funnier is do molag bals daedric quest and hear him say to her that its been awhile since he last saw her in a non chalant way. I'm pretty positive even the dragonborn would walk away.
