So you two have natals charts separated by about three or so months. Which means you have the outer planets more or less lined up together. Jupiter, Saturn, Neptune, Uranus, pluto. And, very important, your moons are almost conjunct.
This is a two faceted situation. On the one hand, you are very much similar, and can read each other easily. On the other, when there are transits you are both hit by them, and when they are easy you are on the moon (so to speak) but when they are hard aspects you suffer together, and during these down spirals you need to support each other.
If we visually eliminate all those asteroids, we can see that all your planets are concentrated between the mars/jupiter trine, so you are very concentrated in your energies, don't easily get sidetracked or go off the tracks.
Your scorpio sun has a conjunction with Saturn, which means also that her Saturn conjuncts your sun. You are used to this type of energy because it is part of you, so it may or may not weigh on you too much, and could work as a stabilising factor. Significantly, her ascendent ruler is Saturn, so this is actually an important link between you that ties the bond. Her Leo sun ruler is the sun, so this sun/saturn conjunction is significant in your case.
She also has her planets very concentrated, in her case between the sun/mars conjunction opposed Jupiter. However, her Venus forms a handle to this, giving her an outlet for her energies. How does this connect up with you? It doesn't really. So how does she address her expression of love towards you?
Her sun conjuncts mars, so she will look for a man with mars qualities, and you are a scorpio, which is perfect. Her ascendent is ruled by Saturn, and you have Saturn on your sun, again her exact image of the perfect male partner for her.
Her descendent is ruled by moon, and your moon not only conjuncts her moon but is on her ascendent. You would seem to be the perfect partner for her.
Your piscean ascendent looks for a mercurial woman, and her mercury is close to but not actually at your descendent, however, it exactly squares your sun, which is her Leo sun ruler, so another important bind.
You both have Ceres on the descendent, so you are both very caring and loving in relationships. Your Juno on both south moon nodes would indicate this is a karmic relationship, you were probably married in the past. However, your mars on her Juno promises lots of fights in a marriage! Her sun/mars conjunction, which in itself is very spirited, also squares her pluto, so she is a very forceful personality.
So is scorpio. Your libra mars will tend to give in for the sake of peace.
Mercury is conjunct uranus, but this can go either way, mercury is "mercurial".
So where is the neptunian quality of the composite coming from? You both have Neptune at the first degree of Capricorn, but it doesn't seem to link up with any planets in the charts. Maybe someone else can shed light on this.
The infamous transiting saturn and pluto will soon conjunct your mutual moons, so there will be a difficult period ahead for you when your emotions will be in an upheaval. If you are planning a wedding, you might want to wait until after that conjunction until you tie the knot.
