Temperance reversed in tarot reading indicates a situation of conflict, a lack of balance and an inability to find a solution to disputes. Your ex may not be ready to reconcile with you yet, perhaps the feelings are still too strong or there is something preventing her from making a final decision. It may take some time for them to reach a compromise.
The Seven of Pentacles can represent the need to make a thoughtful and reasoned decision, and that the choice must be made carefully because it is important to consider all aspects of the situation. The card suggests that you cannot simply decide based on your feelings but must take into account the opinions of others involved in the situation. The alternative solution could be to listen to the other party, understand how they feel and what they want, thus trying to reach an agreement.
The reversed Ace of Wands indicates that you may be distracted by the emotions, thoughts and words of others and unable to think clearly about the situation. You may feel stuck and don't know what to do. The card suggests that you should consider all aspects of the matter in order to make the best decision for you. It is important to remember that ultimately you will have to make the right choice for yourself and it is necessary to take the time to reflect.
Bottom line, the cards indicate that there's a chance you and your ex could reconcile over time, but it's important to consider all aspects of the matter before making a final decision. You need to use caution and consider all available options before deciding whether or not to mend this bond. The most likely answer to the question is therefore no: at the moment it is not certain that you and your ex can reconcile, but there is always the possibility that it will happen in the future if the right strategies are used.
