The Ace of Pentacles indicates that you have the potential to change the circumstances of the current situation. You might consider what you learned from the experience and decide how to act in the future. The card suggests that it may be necessary to introduce some discipline into your life by focusing on your responsibilities to yourself and not someone else's. You may also have to make difficult decisions and choices that can lead to positive change.
The King of Pentacles represents authority and responsibility. Sometimes it is necessary to accept that some things cannot be changed, even if we would like to. The King of Pentacles reminds you that you do not have absolute control over the situation and that you must be realistic about what you can and cannot change. You must be prepared to accept the limitations of people and circumstances.
The King of Wands shows that you should explore the situation further before coming to a firm conclusion. This card suggests that you should pay attention to the bigger context of the situation to discover something new or important information that could influence your final decision. You may discover something useful that you didn't know about before, something that will require further analysis and thought before making a final decision.
From the three cards, it seems clear that the best action to take right now is to take some time to reflect on the situation and evaluate it carefully before making a final decision. You should focus on what you can actually change and how to handle situations that cannot be changed. You should also dig further into the matter to find out if there is anything you didn't know yet or didn't consider in your assessment of the situation. It is therefore recommended that you let go of your ex, as forgiveness may not be possible or realistic based on the circumstances of your current situation.
