The square nature suggests the two planets are not finding it easy to work together.But they have to.Venus wants peace,harmony and cooperation
Uranus is rebellion,independence and "fire starting" etc.
You may be drawn to people who bring your life to a bit of chaos. They may be difficult to "manage" or be very random and inconsistent. There is often "love at first sight" with this aspect and the relationship is formed quickly.
The issues however crop up as frustration. Uranus may pull you two apart by distance(usually)or circumstance i.e the person may be in the process of moving house to another state(when you meet) or moving to another country.
So the square with Venus suggests that things may not go as pleasantly as you are comfortable with. With Venus in Aries, you may want sexual intimacy but settle for phone calls instead(Aqua).
It may also mean that you may be motivated to travel for love. Going out of the country/state to see them. But when you get there, the passion may take its time to get up to par with the momentum of your feelings i.e you are hot and heavy(Aries). They are more platonic and friendly(Aqua)
Whatever the outcome,there is a strongly "inconvenient" situation or something that requires adjutments. But in the same breath, it is not entirely their fault that your life is being disrupted by them.
You may revel in the drama i.e the erratic nature of the interactions between you two.In that you may be bored or restless with anything that settles to "normalcy" i.e you may not feel a strong romantic attraction towards someone who is more convenient or lives closer to you for instance.
If you have Uranus interacting with the 7th/5th or 8th, this may be even more true for you. Romantic and sexual opportunities may be erratic and unpredictable. In that you may have to adjust yourself to doing things a little differently in order to get what what you want.
My ex had Uranus/Venus conj in Scorpio.He travelled quite a bit to see me. And I him(I have Uranus in 8th).
Another before him had Uranus/Venus opp in Sag/Gem. He would get frustrated with having to travel to see me. And it took its toll in our ability to keep our intimacy levels going as he felt I wasn't there in pivotal moments where he needed me.
Its a dicey aspect for intimacy am afraid. Not always a roaring success
