Hey SMW, My ex is also 35 and 36 in August.. so have you put his chart into astro.com and had a look (its free)?? And does that mean your H is also a Leo and you are a Piscean, like us?
Saturn was going through Leo for 2 1/2 years (which triggered my ex's depression) but is now going through Virgo.. so either way, your H will have been hit by that. Also.. he is having the classic "mid life crisis" transit of Pluto square his Pluto then, so I was right about the Pluto effect! It will have been in effect for some time already. Be interesting to see if its aspecting his Moon or Venus (especially Venus as Pluto-Venus tranits are a sure fire indicator of affairs and "3 in the marriage" scenarios)
