You two have some nice synastry, like the 'almost ' Fire Grand Trine involving your Merc/Pluto trine to his Moon.
That is very exciting and makes a couple feel like they can talk deeply, emotionally about anything. It is very intimate and enthusiastic and optimistic energy.
And there is a Mystic Rectangle, which gives stability and support to the relationship. Again, it involves your Mercury and his Moon.
So he feels that you really understand him.
But there is a big problem underlying that rectangle and grand trine. Instability and deceit may undermine this relationship.
Your Mercury has a natal opposition to Neptune, and it is also opposed to his Uranus.
That means to me, that you possibly see men through rose colored glasses. You see the best in people, and ignore any possible problems that may crop up?
The Mercury/Neptune opposition wants fairy tale romance---total love and devotion.
But you may often choose the wrong partners and find disappointment instead?
Which brings us to his Uranus opposing your Mercury, conjunct your Neptune.
I don't think he is very stable or trustworthy. I think he changes his mind quickly abut things. PLEASE, take your time and be cautious.
DO NOT lend him money or give him too much access to your life until you spend a longer time with him.
You have Venus square Chiron, which is where you are vulnerable to be hurt by love. And his Pluto is right exactly on top of your Chiron, the wounded healer.
I really worry that he will not end up being who you want him to be....
