The card for the situation is the reversed Knight of Swords. The Knight of Swords indicates an unstable and unreliable person, who has the power to influence others but has no respect for himself. When he is inside out, it can mean that you or your partner Matthew are going through a difficult time and there may be a sense of confusion or uncertainty in your relationship. You may also be locked down so that you can't resolve the issues between the two of you.

The next card is The High Priestess. This card represents wisdom, compassion and spirituality. It can indicate that you and Matthew are on the right path to overcoming difficulties and evolving together as a couple, although there may be challenges to overcome first. The High Priestess suggests that you both have a sense of trust in each other and are able to talk about your concerns with kindness.

In conclusion, the cards seem to suggest that you and Matthew are well on your way to overcoming the difficulties in your relationship, but there is still work to be done. The two cards encourage you to stick together, focus on what really matters in your relationship, and treat each other with compassion. The most likely answer to the question is therefore "yes", your relationship with Matteo is destined to last a long time.
