Is this a Grand Trine?

I'm a little hazy on what a grand trine is but is this one?

My Sun in Cancer at 1.46
His Moon in Scorpio at 4.58
His Venus in Pisces at 6.43

Rounding them off to the nearest whole degree:
Cancer 2 Degrees
Scorpio 5 Degrees
Pisces 7 Degrees

There's a tiny bit under 5 degrees between my cancer and his pisces with scorpio in the middle. That seems pretty close to me.

I would say this is a Grand Trine. They're indicative of soulmates, you know...

search "grand trines cafe astrology" there's a great page all about them on that website.

Considering I don't know his exact birth time his scorpio moon degrees could be off.
but then I still have my scorp pluto at 7 degrees (so his pisces could complete a trine for me) and his scorp pluto is 1.35 so my cancer could still complete his trine.
