In general, the tens of a suit relate to the completion of a cycle. One interpretation may be that your husband sees that the worst is behind the both of you, and he is looking forward to sharing new challenges and opportunities as they arise in this next phase of your relationship.
To get the most accurate meaning of the card in this circumstance, I would look at the spread as a whole and see how the surrounding cards energy may influence the meaning. Take note of the types of cards in the spread (trumps, swords, wands, cups, etc) to get a better tone of the reading.
If you are still stuck, draw a clarification card. Relate it to the 10 of swords reversed and see if the two cards pair up to form a more solid meaning.
Best of luck
