It seems to me the reading was accurate,
king of coins -shows a man that will love his woman for who she is,
10 of coins -shows that the relationship will be filled with passion and move quickly into the next level of the relationship, 3 of cups -often represents a reunion of a lost love or a new flame of passion.
* however, remember the question, it was what he WANTS from you. I believe the aforementioned reading of the future would trum his desire in the reading.
10 of cups- representing a strong family life.
5 of swords- as i can see indicates that your love is going to be away from you for a while. i believe she interpreted the card as a turn to the negative, however this being the middle card often represents present affairs. however be aware that if/when the relationship resumes, pick you battles and decide what is worth fighting over.
The Tower- this is tricky, depending on the deck. I use two decks with slightly different meanings for each. if you are in a relationship, it can often indicate an abrupt end to counteract the destruction of the relationship more communication is often required. but know that your circumstances are a bit different. This card to me is saying that you fantasy expectations of the relationship need to be re-evaluated to a more realistic stance. Be confident that the tools for rebuilding realistic expectations are already within you, you know what you really need and what you should expect. communicate and make things work out or you may suffer a "crashing tower".
I hope this helped :)
