(Following is not in accordance with standard horary practice and uses whole sign house format)
-querent = 1st house = Scorpio = Mars
-quesited #1 (him) = 7th house = Taurus = Venus
-quesited #2 (his communications, eg, a marriage proposal communication from him) = 3rd house from the 7th = Cancer = Moon
-querent (Mars) is posited in the 12th whole sign house of the chart (house of disappointments), in detriment in Libra = - testimony
-quesited #1, Venus flows toward querent = + testimony
-quesited #2, conjunct Venus, flows toward querent = + testimony
-querent Mars is in a pitted degree (blocked degree) of Libra, and quesited #2, Moon is in a pitted (blocked) degree of Gemini (his communication of a marriage proposal is likely to be blocked/delayed) = - testimonies
Results:
Positive = +2 testimonies
Negative = -2 testimonies
Net = 0
...so, as of this time, the answer is "maybe": however, with significators Mars and Moon both in pitted degrees, delay in this proposal seems likely...
