The first card we have is the Three of Cups. This card indicates that Paolo and his girlfriend have a strong and positive relationship. They may be able to talk openly with each other and cope with difficulties that arise in their relationship. This means that they can work together to overcome the difficulties they are having, but they also need some alone time to figure out how to better handle the situation.
The second tarot is The Fool. This card indicates that Paul and his girlfriend need to look beyond the present and examine their problems with a more objective attitude. They shouldn't stress too much or make hasty decisions, but they should learn to look at things more clearly. Also, they must be willing to accept constructive criticism from each other and have constructive discussions to resolve their issues.
Finally, we have the Seven of Pentacles. This card indicates that Paul and his girlfriend can benefit from analyzing the current situation and finding creative solutions. They have to learn from what they have been through so far to improve their relationship. The lessons learned can help them build a better future together.
In conclusion, the cards suggest that Paul can certainly help his girlfriend in dealing with the current situation, but he should also let her make progress on her own. They should take time to reflect on how to overcome problems and apply what they have learned in the past. So, the answer to the question is: Yes, you should intervene, but in the most constructive way possible by offering yourself support without intruding too much into the situation.
