How these two meet
Aries and Gemini: it started on Monday and by Thursday it was a different thing with the same name.
Something gets started on Monday with total conviction, and by Thursday it is a different thing with the same name, and neither of you has noticed the substitution.
Aries started it and has withdrawn nothing. Gemini reframed it twice, which is not the same as objecting, and both reframes were better. There is no moment either of you could point at where it changed.
What is missing here is the fixed modality, and neither of you has it. Between a cardinal sign and a mutable one, one of you begins and the other adapts, and nobody in this house is built to hold. Not unwilling. Not built.
Mars runs 2.13 years between reversals and turns without warning. Mercury turns back three times a year and spends nearly a fifth of its life going back over ground it has already crossed. Neither of those is a body that stays put, and nothing you have chosen together is still what it was.
Which of you was going to be the one who stayed?
For Aries, the work is finishing one thing in the shape it was started in, even after it has stopped being the best available version.
For Gemini, the work is letting a worse version stand because it was agreed. Say the improvement out loud and then do not make it.
Mars starts and does not look back. Mercury revises and does not stop. There is no third body in this house and there never was.
Between a cardinal sign and a mutable one the thing that does not exist is the one that holds, and no amount of good faith from either of you is going to produce it.
60 degrees apart
Sixty degrees apart, two signs along, and one of the five classical aspects. Signs at this distance always share a polarity, active with active or receptive with receptive, so their elements are the pair that gets on: fire with air, or earth with water. What they never share is modality. The agreement is about temperature and the argument is about pace.

A sign is still a general lens: it says nothing about where your Moon or your Venus actually fell. A synastry report reads your two real birth charts against each other, with the aspects that are genuinely there.
