I'm falling for him and it feels RIGHT. What's going on?

I never felt this way about anyone else before. Falling for him feels RIGHT, like that what is supposed to happen, like it's the natural conclusion of things. It's bizarre. I never experienced this before. He hasn't said anything yet so I don't know if he feels the same.

I have attached our synastry and composite charts. I'm the Sagittarius Sun/Libra Moon, he is the Aries Sun/Scorpio Moon.
