What Venus does in a chart
Venus is the part of the chart that answers one question:What do I find beautiful, and how do I show affection? It describes love style — not events, and not outcomes.
What Aquarius does to it
Aquarius is a air sign, so it moves on ideas and conversation. It is also fixed, which means it holds things. Put those together with Venus and you get loves as friendship first — independent, systemic, odd-angled, applied specifically to love style.
Aquarius is ruled by Uranus, so this placement tends to be coloured by independence as well.
The useful version
Placements are not verdicts. This one describes a default setting, not a limit — the things listed above are what you do when you are not thinking about it, which is exactly why noticing them is worth something.
