The synastry is a mess! The only aspect I see that may provide some relief is the sun conjunct mercury. You guys may be able to communicate your differences and work through some of them, but there are too many challenging aspects overall. You may be drawn to this person because they have a problem that you think you can help them with. You may see them as wounded in some way and want to play a saviour role in this relationship. (your moon- conjunct his chiron) . But just be aware that this is not enough to hold a relationship together.
The house overlays in the synastry are not strong enough. A lot of the planets fall in the 11th, 9th or 12 houses. 11th can be good for a friendship and may seem pleasant enough at first, but are not enough to hold a relationship together. You need planet overlays in each others 7th, 1st, 4th, 8th, 5th (a lot of which are relationship houses). There's also a lot of stressful aspects that over time will cause the breakdown of the relationship.
The composite is a little better, there are a lot of positive aspects between the moon which will suggest an ability to understand where each other are coming from emotionally and work through some issues. But again the t-square between pluto, saturn and mars (which are all malefic planets) is worrisome. Also in the composite the planet placement isn't strong. The first red flag i see is saturn almost exactly conjunct the DSC which could represent divorce or separation. Or something like an authority figure, society etc. may make it difficult for this relationship to work. Most of the planets are in non-personal houses (the 9th, 10th, 11th, 12th). The moon is placed well, but again one positive up against a list of challenges will be difficult.
Also the pluto opposite moon aspect in your natal chart is something that may cause a disruption to your relationships. You may want to control how things work out or manipulate people so that they stay in your life. Your emotions can get the best of you sometimes.
