Is he seeing other women?

I’ve been seeing a guy here and there on our commute and I feel we’re attracted to each other, but I’m wondering if he’s currently entertaining another woman (or multiple)?

Not sure how to read this, I would say yes because of Venus in the 7H but his sig Saturn doesn’t make any aspect. If we see Venus as his co-sig, he’s aspecting me as Moon, Saturn makes conj w Merc but my sig Sun ‘got to him first’ w the 0 degree conjunction and doesn’t make any other aspects besides those two planets.

Any ideas? Is he seeing other people romantically? Thanks in advance!

It doesn't seem so, as he is symbolized by Saturn in his turned 12th house, combust the sun. More like, I don't know if he feels emotionally prepared to start a new relationship. Your significator, the sun, is past Saturn now. He was probably just a flash-in-the-pan curiosity.

In addition to waybread's comment, moon leaves the trine with Uranus, co-ruler of the 7th, and squares mars.
It was a passing flirt.

Since the separations are happening from my sig is it safe to assume the fleeting curiosity would be on my part? I would assume so since he receives sun by sign (ruled by cap) but moon is in fall in his sign... I find him attractive but not necessarily excited at the thought of dating him, I have just been curious to see if he has options.
