The Sun square Saturn synastry aspect creates a certain tension between the two parties involved. The Sun person wants to express themselves (according to their birth chart’s sign and house) and shine in their own way, but the Saturn person obstructs and hinders, unwilling to let this happen. Such a dynamic does not bode well for the relationship, but it may not manifest as severely if there are other supportive elements in the synastry chart. Additionally, with Saturn, it is often the case that things improve over time, provided both parties put in enough effort. Saturn demands that the issues it touches are taken seriously, and work is done to improve them. In fact, the Sun square Saturn aspect in synastry can eventually become a very effective and practical element in the relationship if its challenges are overcome.
Saturn, of course, has its reasons for its obstructive behavior. Often, these are related in some way to the Saturn person’s fears, or perhaps they see the other person’s actions as childish or irresponsible. If the aspect appears in a parent-child relationship, this is a very natural manifestation. In this case, the parent (Saturn) is supposed to restrict and control to ensure that the child does not engage in “irresponsible” activities. In a romantic relationship, a similar dynamic may be experienced, and likely there is something for the Sun person to improve in their actions. Otherwise, the Saturn person would not have entered their life. Another possibility is that the Sun person needs to find a stronger internal authority within themselves (Sun) and not do what the other demands. If this is the case, there are likely indications of it in the Sun person’s natal chart.
The Sun square Saturn synastry aspect brings solidity, stability, and patience to the relationship, as indicated by the mutual needs. However, the Saturn person must be very aware not to excessively restrict the Sun person’s childlike joy and energy. If this happens, the Sun person may become depressed and perceive the other as a very heavy and dull individual, possibly leading to the end of the relationship. Moreover, the Saturn person also derives warmth and joy from the Sun person, even if they may not want to admit it. This situation reflects a common phenomenon in relationships: initially, one falls in love with a partner’s characteristic x. Over time, this trait becomes a “problem,” and the person wants to unconsciously suppresses it. Then, both are in a situation where they are annoyed by each other’s presence, wondering what went wrong. The issue lies in the fact that people did not objectively examine themselves but focused on the other’s criticism (Saturn) or the other’s “irresponsibility” (Sun).
