The Ten of Cups card shows a family gathered around a table. The fact that the family is close and in harmony indicates that there is a sense of intimacy and stability in the situation. This means that the relationship has the potential to be a lasting one, as long as both partners put their effort into it and are willing to invest time in building a solid relationship.
The Seven of Wands card shows a man who is dealing with an internal conflict. This indicates that the relationship could be tested by conflicting feelings or by the presence of external elements such as other ex-partners or people interested in both. As with any relationship, it is important that all partners involved are committed to discussing their points of view, addressing any problems and finding common solutions.
In conclusion, the chances of having a lasting relationship with someone who has already had many partners depend a lot on the personal commitment of the partners involved. It's important to maintain intimacy and harmony within the relationship, and to address any issues with honesty and mutual respect. If both partners are willing to invest time and energy into building a solid relationship, the relationship can become lasting.
