My personal take on Synastry is that it should be like bootcamp for the real-deal, the commitment (composite).So, without any hard energy in Synastry to make things HAPPEN, I see relationships fizzle quickly, or become pretty ambivalent/boring.
This one... while pleasant, does not have the real, raw energy needed in my opinion to make a bond form. I'm not saying that dating has to be HARD or painful before a real commitment is formed, but there needs to be some real POW, passion, oomf to make two people recognize each other as something important.
What I see is , right off the bat, a total lack of energy from the luminaries. To me that just looks like a dim lamp. Comforting... but not enough to draw my attention. I couldn't totally figure out who's who in the chart you added, but it doesn't really matter: Sun energy is realllyyy way too empty for any ongoing relationship. There is a sextile of Sun/Saturn, but in my humble opinion, Saturn needs to be stronger in synastry, and then gentler in composite later on. It is, afterall, that glue that forms the bonds.
I see almost zero Chiron energy (not that I am a huge fan of chiron, but I always consider that an indicator of a karmic bond). I see very little Juno energy - the marriage/commitment asteroid.
More importantly, Moon is too empty/ unaspected as well. There is a lack of moon from his side, although it does overlay your 5th house (if I'm looking at this right), which is your fun/romance house, so I am guessing you feel an emotional link to him and attraction therein. Your moon is in his 1H, so I think maybe your emotional energy is supportive to him and makes him feel good. So that could work well for a friendship. But all moon orbs are relatively wide, so I don't think this is likely to be a super-close bond. Also, the square of Moon and Uranus alwayyyysss makes me cringe.
There IS some venus energy here, but really, just in semi-sextiles... again, just nooottt enough. You need the attraction to each other.
There is, kind of surprisingly, some strong Pluto here. But that can be tricky, as it could lead one person to feeling dominated and left out to dry by the other.
And, going back to my initial point, the lack of Saturn strength here just wouldn't create enough glue for a longterm bond, in my opinion.
I'd guess this could be a very easy-going friendship, but not a deep, emotional connection at all. Curious to hear what the relationship is like to you in reality though? Can you give a little more background?
