Looking at the reverse of the King of Wands card, we can tell that the personal problems of your business partner will not necessarily affect your business. This card indicates that there is a strong possibility that personal situations will remain separate from your professional relationship. You may need to clear things up with your business partner, but leave open the possibility of maintaining a good partnership between the two of you.

On the other hand, we have The Tower reversed, which may indicate some difficulty in keeping professional and personal aspects separate. This could cause tension in your business and lead to misunderstandings. It is important to be attentive and maintain a constructive dialogue between you to prevent this negative aspect from affecting your cooperation.

Death is a sign of significant change, so it's possible your business partner's personal issues are having an effect on your business. However, there is also a positive aspect to this card: if handled correctly, problems can lead to a new level of mutual understanding and a renewed spirit of collaboration.

Finally, we have the Knight of Pentacles, which can indicate that if you handle the situation correctly, you will be successful in your business. The Knight of Pentacles is encouraging you to act with caution and make informed decisions to prevent any problems. Additionally, you should be open to dialogue and communication with your business partner to ensure that all issues are resolved amicably.

Bottom line, the tarot suggests that your business partner has had some personal issues that could affect your business if not handled properly. The key to avoiding problems with your business is to be open to dialogue and make informed decisions with your business partner. The end result depends on your ability to work together to find shared solutions to any difficulties you may encounter. Therefore, the answer to the question is: yes, your business partner's personal problems can affect your business if not handled properly.
