Yes.. I have a friend and my Chiron is conjunct her sun and her Chiron is conjunct my sun. It’s an important friendship and us hanging out has healed us both significantly.

I find Mars in synastry to be intense.

Don't know about soulmates though

I would be surprised if that could be forecast.

Hadn't really considered Mars.  What Mars aspects did you find intense?

Mars in aspect to my N. Pluto. But I think pretty much wherever it is I notice it.

I don't know if my Mars impacts others. My impression is that it doesn't especially. My Mars is fifth house though so perhaps it is best expressed through creativity and I don't do the creative things I would like to because of time/ energy etc.

Pluto - Moon & Venus & Mars........ I want to feel our souls merge as we devour our hearts. 

I love you Pluto!
