This is the most positive reading I've come across in a long time, maybe ever. The lovers card is one of the simplest cards in the deck-the card of human love. Throw the 2 and 3 of cups in there and we're talking about a relationship ordained by the gods, supplying reciprocal merriment, solace and healing. I don't know what the future has in store for you specifically, but you should take great solace in this spread. Whether or not he proposes to you in the immediate future, I suspect you have struck gold with this one and you should definitely just relax and be grateful to have found such a compatible lover. And be patient - because your feelings are mutual.
Having said that, I get the impression you'll be married soon; it's a slam dunk as far as readings go, but the Lovers card doesn't entail marriage. It entails love, just as marriage does. The ingredients are there, for both of you, so carry it like a faberge egg. And congratulations, and let us know when he pops the question!
