Of course it always depends on the individual.However, having a solar arc Uranus or Neptune in conjunction/square/opposition/even quindecile to natal Venus/Moon/ASC/DESC/ruler of 7th house can spell trouble (though with Neptune it could also feel soulmatey).
solar arc Pluto or Saturn can be difficult, too; depends on the foundation of the relationship. Sometimes it even strengthens a relationship and makes it VERY deep and comitted, at other times, breaks it up.
If you have such solar arcs (and possibly more than one), the secondary progressed Moon or outer planets transits, espcially to the solar arc/ natal aspects can act as a trigger. Something has to change and it will change. The positive way would be to implement the change yourself, as a couple. If not it will seem like the change will be imposed on you. And especially in the case of Uranus that often is a sudden disruption/ breaking up, and in case of Neptune an erosion/fading away of that which is there.
Uranus in strong aspect to Sun and ASC and ruler of 1st can be quite challenging, too, as it triggers a need or urge for individuality, evoking a certain self-centredness, which could be detrimental to a relationship.
Personally I think though if both people are highly Uranian in nature, it might actually become them, and they might like it.
If they are highly Saturnian or Plutonian when it comes to relationship (check especially VEnus, 7th house, ruler of 7th house, 5th house, ruler of 5th house and possibly 8th house for finding out), the Uranus transit or direction or progression might feel like a tremendous shock, disrupting the very foundations of their lives.
Also if a solar arc or progressed or transiting aspect repeats a natal configuration, it will be very significant.
For example sa Neptune square natal Moon with Transiting Neptune conjunct natal Moon (seems a bit like overkill, but it happens. lol) and you natally have Moon trine Neptune, have a VERY close look at what is happening in the natal. Where is this Moon-Neptune aspect falling? Which signs, houses? Which houses are ruled by Moon and Neptune? Which other planets aspect it?
That might give you an impression how it could manifest.
Davison writes in his book on progressions, a very old one, but boy I learned a LOT, and still am processing it. lol, that a progressions (I suppose smae goes for solar arc) will usually manifest the way the natal aspect dictates, which means if you have a harsh progression but a rather nice stimulating natal aspect, the effect might not be as dramatic or disruptive as the aspect had you believe, it gets a little more productive and smoother.
However if you have a nice harmonious progression (let`s say pr Venus trine n Pluto) but the natal aspect if in existence is harsh (Venus square Pluto), watch out, even the harmonious trine might wake up some sleeping dogs, though at the same time could be helpful in transforming the aspect.
Of course the harmonious aspects in progression or solar arc are usually not that impressive; however I believe IF they mirror an existing natal aspect, they should not be underestimated.
