I am appointing the 5th house lord Mars for him as well as the Moon, as is the Moon-your Co-ruler: Object Romance. Is he a prior friend as briefly mentioned...then he would be the 11th house and you would look at the houses of romance from there. He is not a stranger 7th ...she knows him.
His thoughts about the social gathering is ruled by Mercury (7th house rulings) whom is in the friendly sign of Aquarius in your immediate future 2nd house with Planets, Pluto (physical attraction) Saturn (serious-somewhat limiting..), Mercury (conversations about these situations..) that are centered about you ..Your lord of the 1st house is Jupiter. (Are you a bit self conscious?). Jupiter is among those planets with Mercury coming up behind. Moon in the 10th, relationship subject matter, emotions (Moon) openly expressed, Moon in the 10th house will trine Mars his lord of the 5th house (romance) and the social planets in the 2nd house at someone's (a friends) home? Or maybe that is yet to come about?
I wouldn't discount the fact that romance is out of the question, as neutral implies. Mars in Taurus can come off as being a bit shy at breaking someone's heart (Mars in Taurus is also in orb of the square with Venus, although it is past, Venus is depositor of Mars there relationship is easing up from some discord) you might be careful if you are going to take a chance of having more than just a tete' a tete' with him, (don't throw yourself at his head in other words unless you are prepared for just a fling) he is among friends and boys will be boys, is he looking for that special person...are you it, I don't know I don't think so? Mars will be in Gemini (flirty) and squaring Venus makes for an obstacle for love of your life type of union if you are looking for that type of relationship with him. He wants to shop about, Mars in Gemini is fickle at times. He could even be hiding another love interest, Venus is Combust (hiding) the Sun.
The aspects that are hopeful for fancy are the ones Venus makes by sextile (opportunity) to Uranus in the 5th house. But then again, Uranus is in his fall. There is a mutual reception Uranus (Taurus) makes with Moon (Libra), Uranus is in harmony (Doris Chase Doane "Modern Horary Astrology" with Moon who in exchange with Uranus is exalted in his place,) but it is by opposition. So again, I would caution throwing yourself at his head only to have the expectations be on a sexual attachment.
I hope you have what you want out of the actions you might put in place. Just be aware and forearmed, after all what man will say no to attraction?
Sincerely
