Hi Johanna! I agree that those are great cards. Probably the best that you could've gotten. The only thing is that it's almost "too" perfect lol. I mean that just to say that there might have been a shuffling issue or something like that to get that bold of an answer. You could always wait a few days and ask again and see if it's still a positive answer.
As for the clarifier, it's just something to give more information. So I would see the three of pentacles as telling you this positive outcome will be based on both of you working toward a reconciliation. It doesn't have to mean working "together" on it. Just that both of you would need to make some concessions or possibly compromises in order to reconcile. Also, the three of pentacles sometimes means asking for advice and/or receiving counseling or something like that, depending on the nature of the question. The meaning of the card has an apprentice, an architect, and the customer (or boss) all looking at something like a blueprint for future work to be done. It implies making a plan with multiple people who are involved and setting your sights on the work ahead. Since it's a relationship, I would see it as possibly telling you it'll be helpful to run this by a therapist or someone who can give you advice on the matter from a practical standpoint. They might be able to give you some realistic ideas about how to get this thing rolling and back on track.
