The first card is the Queen of Pentacles, representing someone who expresses loving and supportive demeanor. The nature of your relationship with Carlo is probably very sweet and loving. The Queen of Pentacles can also indicate that you are protective of Charles and want to have a loving and respectful relationship with him.
The second card is the reversed Eight of Wands, which suggests that there is something standing in the way of the relationship between you and Carlo. This could be an internal conflict or an external issue, such as social pressures or feelings of jealousy. It could also be a practical issue, such as limited times to meet or different expectations on how to handle the relationship.
The last card is the Seven of Wands, which is a difficult problem to deal with. But even if difficulties arise, this does not necessarily mean that a solution cannot be found. The Seven of Wands indicates that you need to be creative and bold in finding a way to overcome the obstacles that stand between you and Carlo.
Looking at the three cards together, it seems that the nature of your relationship with Carlo is essentially positive but there are some hurdles to overcome in order for you to fully enjoy your relationship. There are difficulties but there is also the possibility of finding creative solutions. The most likely answer to the question is therefore: Yes, you can have a loving relationship with Carlo if you overcome these difficulties together.
