Hi
marie35 ,
Just a guess from an amateur...
I think this is potentially a deep and enmeshed kind of relationship. Your nodes are exactly squaring his. Your north node is in Aries, ruled by Mars. So you are destined to learn more about Mars, how to harness your energy and direct it towards your highest goals. His north node is in Capricorn so the same applies with Saturn.
The Mars energy here is prominent and somewhat volatile. Your Mars is the apex of a yod with his Mars and Uranus. Composite Mars-SN is conjunct your ASC, composite DSC on your Aries NN, your Mars is widely conjunct his DSC. His sun-Mars opposes your sun and is conjunct your Pluto. Whew! It's a lot. In some ways this could even be ideal, physically...except I think there could be some problems with communication. Because your Mars is in Gemini, communication is paramount. I'm saying, if you two find yourselves arguing, the physical-romantic aspect may not go well, of course. And then the other issue is, with Mars conjunct Pluto in synastry there is a higher risk for physical escalation. Maybe not violence but roughness.
Let me try and put a finer point on this...the communication, frustration, and arguing theme.
With moon trine moon synastry, your emotional needs are in sync, so it's not like you have to rely so much on words to get on the same wavelength, and your Mars is in a grand trine with these moons, so you are motivated to keep an even flow. Your sun/sun opposition also creates some basic understanding. But when things get difficult, you may find that verbal communication is more difficult than it should be, and upsetting. Your Mercuries do not aspect each other. Composite sun conjunct Mercury, in my experience, can create a sort of unspoken agreement to agree. You feel like you have to agree. Even if you DO NOT agree, to the furthest extent possible, you may still feel this urge to streamline together and form a cohesive narrative that makes sense to both of you. It can seem really comfortable and then quite disturbing when it's falling apart. When it's good it's great and when it's bad, it creates soul upheaval.
Back to Saturn being a critical issue for him. Your NN-Mercury-Jupiter in Aries, sextile Gem Mars, has a lot to say. His NN in Capricorn thinks it knows best and has a lot to teach. Probably, for the most part, you recognize his sensibility. Your earth sun gets his earth NN. But if he wants to "crack down"...you have no use for that. That is going to hold you back. His Saturn is conjunct the composite sun-Mercury-Juno and it squares your sun, and you may feel this like a bunch of dead weight. The more you try and communicate your issue, to break free, the more he might try and "save" the situation by applying more Saturn energy, not out of malice, but it's like the only thing he feels can really work. He really trusts it, sincerely. Composite Saturn is conjunct Neptune on his NN so he might feel like this is simply his destiny, end of story. Composite Chiron on his SN might make him feel like he knows how to heal this. In a way you are both right but your needs are clashing.
I'm getting way ahead of myself, it's like imagining a relationship three years into the future. Anyway I can see the allure (Gem Venus-Jupiter sextile SN-Mars, for one thing...looks intoxicating)...comp moon on his ASC in Sag, lots of Jupiter good times here, my concern is just that when it goes bad it might be really frustrating (communication issues) and finally possibly even dip into a physical aggression situation now and then. Not necessarily abusive but there is a little red flag, I would guess. Not about him, I don't mean to insult anyone I don't know, but the relationship dynamics might get extra physical.
Hope some of that resonates or is accurate. Good luck
