Welcome! 
A friend of mine had one month of passion with a girl and then they both decided they were going to marry one another. I've never seen any two people move so fast and am trying to understand the triggers for that instantaneous partnership in their astrology (male outside, female inside in the chart below).
It happens sometimes.
Has anyone experienced this type of superfast relationship start?
Not quite that fast no.
What beyond the push/pull of the aspects might cause this? I can't upload their composite chart but they have a Saturn/moon conjunction and also Uranus and north node in the 4th house, a sun/Neptune conjunction in the 5th house, a mercury/venus conjunction between 5th and 6th house, Jupiter near the ascendant and then mars in the 11th opposing their sun and mercury. It seems like their fast union is going to be quite fortunate and long term for them based on the 4th and 5th house composite stelliums. Any words of wisdom or insight to help me understand this better? Thank you!
Well, to start with, they both have Saturn (loosely) conjunct moon, and the composite has it as well. They get each other on that level. On the synastric level, his Jupiter and his moon are conjuncting her ASC, and her moon is conjunct his DSC (assuming correct times all the way around). Better is that her sun is in the opposite sign from her moon and his sun is trine her moon by sign. So that's nice. Her Venus is opposite his sun/Pluto (and her Mars trines!), his Saturn is opposite her sun, his Venus square her Saturn/Jupiter opposition... Oppositions are a big deal here - her vertex is conjunct her nodal axis and their Junos are connected to it.
What might be making it superfast here though, is that she's got Juno conjunct Uranus, and he's got Juno trine Uranus - quick marriage seems to be baked in.
The composite has some fairly hilarious midpoint connections: Jupiter/Uranus = Juno, Sun/Juno = Saturn and my favorite, Venus/Uranus = Sun, all of those being conjunctions.
Speedy. Good luck to them.

Instant attraction is usually about our shadow material being seen in someone else. Oppositions are a great place to find shadow material.
The person in blue looks like they have great potential for being a love addict ... Pisces Sun in 7H combined with Aries Venus and Gemini Mars ... suggests someone who dives into relationships without thinking too hard about the consequences. Also the Saturn/moon in Aqua is a tough place for intimacy and meeting her own emotional needs.
The other person has Sun/Pluto in Libra in opposition to the Aries venus so may well have felt this is the person especially if she was coming on fast.
Bear in mind that if this is a recent relationship - uranus is hitting both of these so it would explain the instant attraction. But therefore it may not last.
The danger in this synastry is that his Scorpio Mercury/Venus won't get enough depth or fulfilment from it especially with the square to that Aqua moon/saturn. Or when he starts trying to dig, she'll run. That said he has Uranus close by to them so he may be quite comfortable not getting too deep either.
Hi all,
Thanks so much for your insights. What a combination of aspects they have. I hadn't looked at the asteroids so appreciate the information your analysis provided!
From her side, she's been in live in relationships since her teenage years and had a baby with the last one after assuming they would get engaged and married so there is a history of diving in pretty deeply. For him, his need for total insight and knowledge is strong and he's insisted on total information sharing so I think his Uranus is not quite close enough to lighten up that need. They are a tight family unit now so hopefully they'll be able to navigate any sudden changes or transformations that may be on the horizon.
Thanks again!
They have a loaded synastry, a lot going on!
Her Pluto square His Mars, His Pluto opposite Her Venus, His Neptune opposite Her Mars, His Mars opposite Her Moon, Her Sun in his 8th house. This is hot, but so obsessive and potentially volatile as well. I bet they don't like to be apart from each other for long... with this much Pluto, it becomes all-consuming, very fast. The Mars sextiles and trines make for a good physical connection and attraction too.
Saturn is the planet that wants to make things official (like marriage) and they have important Saturn contacts. His Saturn opposite Her Sun is a big deal, and Her Saturn is also square His Venus. Very binding aspects that can create a sense of responsibility and commitment to each other early on. Plus, he is a Pluto/Sun Libra, and Libra is the type who likes marriage and commitment. Saturn/Moon would like it too.Feel more secure with having things be official.
They also each have some impulsive elements in their natal charts. He has Uranus square fiery Mars in Leo, so he may have an impulsive streak, quick to act. Her Venus in Aries would tend to be impulsive in love as well, they can fall in (and out) of love quickly, not necessarily thinking things through.
There are markers for mutual obsession here, and he is already inclined to being a little obsessive with a Scorpio stellium with Venus, and a Sun/Pluto conjunction. Her natal chart is a little lighter and more freedom loving than his.
They have some good aspects here, but I can see this as a very all-consuming attraction. Watch out for those Neptune aspects... it is good he is asking questions. His Neptune is square Her Sun and opposite her Mars. It may take a little while until the veil lifts and they see each other more clearly.
