Eliza, I don't mean to knock your socks off, but this is actually one of the better astro mach-ups I've seen. Your suns (ego campatibility) and Mercuries (communication) are squared, which isn't so harmonious, but they are definitely connected. Your moons are probably broadly sextiled, which is a great aspect for feeling "at home" with someone. Your Venus conjuncts his Mars, and your Mars sextiles his Venus, so the romantic attraction looks 2-way. Your Jupiter conjuncts his sun, which is a real feel-good aspect; although it can also mean a mentoring sort of relationship from the Jupiterian.
Just a few caveats, though; and with so little info to go on, some of them could be inapt.
1. Pisces people can be rather shy, and liable to retreat behind a defensive shell. Possibly he's been hurt before and unwilling to try again (note his Chiron conjunct moon square Mars). Consequently he may not feel ready to start a serious relationship.
2. You, on the other hand, have that very loaded 7th house, including your very strong moon in Cancer. Probably you feel most like yourself when you are in a committed relationship, even marriage. You have a very outgoing Sag ASC; and with Uranus in the first, is it possible he feels a little unsettled around you? Your Mars opposite Venus in the 8th may give you a high libido.
3. Of course, there are the usual possibilities about why even a match made in heaven won't work out. I don't know whether you know if he's: (a) gay or straight, (b) is involved a strict religion, (c) in a long-term relationship with someone else (possibly even with little kids at home), (d) he is very conservative, whereas you are very flamboyant, or (e) or whatever.
If you see a green light for #3,quite possibly you can "speak" to his chart in very subtle ways; maybe invite him to a party or out to dinner with a group of co-workers, &c.
Good luck, Eliza!
