Friendly, person-centred readings by a practitioner with over twenty years experience.
The interesting thing here is your reason for ending the affair. You say this was because 'it was the better thing to do', but the cards indicate there was not only a moral reason. It's not as abstract as this; something has been happening to you, changes in your life recently, that have led to this decision. There's a sense here of you arriving at a new level of maturity and success. My guess is that this change of circumstances – which has only recently begun, or is only now beginning – is what actually triggered your break from the past.
Looking back, the cards suggest that the relationship was sometimes not that great – or at least, that's how it appears now. There's a suggestion of something arid, immature, and a person who did not always impress or inspire you. No wonder you decided to act, given the current increase in your own self-confidence and prosperity.
In the future there is another figure, another relationship, with someone who in many respects is the opposite of the person from the past. This person, in the future, will have the ability to make a deep, inspiring impression upon you. This person has a sharp inner vision, and is capable of succeeding precisely in those areas of life where the previous person tried to make a mark, but failed. (It's not clear whether this person is already known to you.)
In conclusion, the cards suggest that it may be helpful to re-visit your reasons for ending the affair, and look particularly on what is changing in you at the moment, because these changes were the real reason that you took the action you did. The current phase of change is likely to take quite some time before it is finally completed and fully established (at least a few months), but the immediate future looks promising. If it's not apparent who that person in your future is, you may need to be patient until they arrive on the scene. The indication is that the changes in you that have begun will be over or well under way before this other relationship makes its influence felt.
I wish you all the best!
