I honestly hope they are very happy together and experience as little stress as possible in their marriage. Perhaps they both might yet put an end to suffering in this life? Who knows?
If a husband and wife were both practicing, and supported each other in the practice, they could both benefit. It's complicated and has it's challenges, but I don't see romantic love as the big scary bogeyman it is often made out to be, anymore. It could be that, some folks are better of in a relationship, than alone - even for the cultivation of the practice. Which is better: sitting in a monastery thinking about women all day while you are trying to meditate, or, getting married and being with a woman, then meditating so you can have a break from her? Out of these two alternatives, I would choose the latter. (I'm not implying that the Venerable Ajahn had to make this choice, however.)
Then the Blessed One, picking up a tiny bit of dust with the tip of his fingernail, said to the monk, "There isn't even this much form...feeling...
perception...fabrications...consciousness that is constant, lasting, eternal, not subject to change, that will stay just as it is as long as eternity."
