Hi Venus.
You didn't mention the meanings of each position for the horseshoe, but as far as I'm aware, the most common meanings for each position run as follows:
1. The past.
2. The present.
3. Hidden influences.
4. Obstacles.
5. Environment.
6. Action to take.
7. Outcome.
Now, normally when beginning a reading, I will first pay attention to the Major cards, if any, that turn up, as these will usually give us the theme of the reading, but in this case there are so many Majors!
With so many Major cards afoot, it seems that this man is set to be a powerful influence in your life, something huge has brought the two of you together.
There is only one Minor card, which is the Two of Cups, so perhaps we should focus here to begin the reading as it stands out. This card falls in the position which relates to your surrounding environment, and so refers to others, and especially him. There is such great potential for love to develop between the two of you, soulmates indeed! You ask if there is the potential for anything to come of this, and there most certainly is.
For the past you have The Magician, which as a past event may show the meeting between the two of you, and The Magician suggests that there is something magical about this encounter. It's as if your meeting was arranged by some higher intelligence. The funny thing is that you met as a chance encounter while out walking, but The Magician is so very decisive and willfull, and leaves nothing to chance, so I feel that there is in fact great purpose to your meeting and that this event was not as random as it seemed.
For the present time, you have The Sun, so do not fear that your hopes for as romance between the two of you are misguided, because with The Sun, everything is made crystal clear, so do not doubt yourself. The Sun is the source of light and life, so your current speculations upon what may happens between the two of you are very right. This is such a wonderful card, and promises clarity of vision in the way that you are looking at things now.
For hidden influences, The Empress turns up, and The Empress represents women in general, and so may show his current casual girlfriend, but do not worry about this, because in light of such a good set of cards I do not feel that this can be so negative, as 'hidden influences' in this case may show that this casual girlfriend may stay in the background, but see to it that this does not mean that he is keeping women secret.
For suggested action in the midst of this situation then you have the Priestess, which is the opposite type of woman to the Empress. It is therefore perhaps suggested that you remain chaste and precautious for the time being, keep your feelings simmering away to yourself for the moment and don't reveal too much about how you feel, and don't jump into bed with him just yet, until you know more about his motives and circumstances, and what is going on with this other woman.
As he hides an Empress, see to it that you hide your Empress also for the time being.
Should this action be followed, then you have Judgement, which is a summary analysis of the situation. If you manage to hold back for the time being, keep quiet and just observe the situation unfold, then you will come to some summary conclusion about this issue, you will make informed judgement about this man, and perhaps the reason you are warned to have some reserve in your involvement may be because you could end up being hurt otherwise - it depends what it is that you are set to discover about him which will allow you to judge him fairly.
Having said this, should these precautions be heeded, then I believe that there is great potential for you to have a deeply involved relationship, and it seems that there are undoubtedly some major spiritual lessons to be learned from each other.
Hope this helps.
