(Following is not in accordance with standard horary practice and uses whole sign house format)
I'll "cut to the chase" and use the Part of Marriage to delineate this question
-querent = 1st house = Leo = Sun
-quesited (him) = 7th house = Aqaurius = Saturn
-the Part of Marriage-POM- (ascendant+7th house cusp-venus) falls @ 24 Pisces
-POM is in a cadent house (the 9th) = - testimony
-querent (Sun) flows away from the POM = - testimony
-quesited (Saturn, posited in Libra) is in sign opposition to the POM = - testimony
-Moon flows toward the POM = + testimony
-Mars, significator of the POM, flows away from the POM; querent's significator the Sun also flows away from Mars = - testimony
Results:
Positive = +1 testimony
Negative = -4 testimonies
Net = -3 testimonies
With a net -3 testimonies, the indications are negative (during this period of time) for a really lasting relationship (similar to a marriage) according to my delineation of this chart. However, in the future this situation might change, but for the current period of time my answer to your question is, no...
NOTE: during this period of time he might well want to get back with you; and in fact this might happen; but the deeper, longer-term, more permanent trend, shown in this chart, is ultimately negative for a positive lasting relationship (that's why I chose the Part of Marriage as my primary significator for this question; I wanted to see any trend toward a deeper, more permanent relationship; and the trend is not in that direction)
