Upright Meaning:
In a family-specific spread, the Four of Pentacles often indicates that you are holding on to past issues with family members that are causing you to isolate or maintain boundaries with them, or that it is time to establish boundaries with a family member because of these past issues.
Reversed Meaning:
Family-wise, Four of Pentacles reversed is a pretty clear opposite of the upright meaning – it is time to let go of resentments you have with family members and try if you can to heal or mend your relationship. If you have been No Contact with a family member, perhaps now is the time to reach out again, or they could be reaching out to you.
Keep in mind that if this is an abusive situation, you are not under any obligation to accept them back into your life; in that case, a release of anger and resentment without any further contact with them could be in order, so that you may move forward.
