Well, you surely have some strong attraction-aspects:his Eros conjunct your Psyche exact
his Venus conjuncty your Pluto
his Neptune conjunct your Venus
his ERos conjunct your Venus
his Juno conjunct your Eros
his ASC conjunct your Mars
your 5th house ruler conjunct his ASC ruler
your DESC-ruler conjunct his ASC-ruler
his DESC-ruler conjunct your IC
his 5th ruler and 8th ruler trine your Moon, which rules your ASC.
There are some things that need to be thought through more thoroughly, inlcuding:
his Pluto on your IC.
his ASC-ruler square your Saturn
his Saturn square your ASC and opposite your 8th ruler
his Venus square your Saturn
Pluto on the IC is a very deep aspect, but since Pluto is probing by nature and IC the deepest part of your psyche, the sheer intensity and intimacy can sometimes feel overwhelming.
The Saturn-squares can indicate a certain block or holding back on both parts, probably out of a certain fear.
The question is where does that inner block come from?
For this we have to take notice that both your Saturns are in the natal 12th house, so your composite Saturn will be in the 12th house,t oo. Either the blockages may come from subconscious things, or even from a past life.
With Saturn in composite 12th house, maybe a possible romantic relationship has been thwarted or prevented by authority figures or circumstance.
his 12th house ruler conjuncts your Venus, so I am pretty sure at least partly the romantic attraction has already been there in a past life.
Speaking of past lives, he has SWINDLE on the SN, conjunct your Sun.
So a possible cheater scenario may have come from the past, maybe that is where your fear comes from? The conjunction is not unbearably tight of his Swindle to your Sun, so I wouldn`t worry too much.
Another thing that I found interesting is his Sun-Jupiter-conjunction closely squaring your Juno. Of course this is some kind of a soulmate aspect, but issues of equality, balance in a relationship and jealousy / posessiveness might arise.
As you probably know Jupiter was cheating on Juno all the time, so yes, it could point to infidelity, but it is not a must of course.
Juno and Jupiter have been passionately attracted in the beginning and during their honeymoon, which lasted 300 years!
The problems arose when they had to return to the "world" and arrange their living together in the "real world". And it was an ongoing cyclic struggle, in which Juno fought for attention and respect, while Jupiter was philandering.
Now, it does not always have to be women, Jupiter here could also be occupied with a hobby, his work, health, his friends anything and you will have to find a way to share your time.
In a square aspect it could denote some clashes in that regard, a bit of bickering even.
But unlike Lilith, who also fought for equality in a relationship, Juno did not walk out on her husband, she stayed through it all (except for one time when she really has had it and left him for quite some time; then it was him who followed her and brought her back, so the game could start a new); so I think Juno is a sign of struggling for coming to an agreement WITHIN the relationship, the will to really work for it.
And in this instance it really is a soulmate and marriage asteroid, as it relates to that kind of dedication and commitment.
IN a square aspect this might be challenging at times, though.
