When you consider the context of the question as an energy moving to you personally, you should take the subject matter of the house you are wishing for to meet up with you in the future as some conformation.
Lilly takes Jupiter (7th Pisces lord) with host Venus of Libra (natural lord of marriage) as the initiators of the 7th house actions=marriage, lords of Libra and Pisces. These two lords have to apply favorably to your host Mars of Aries as natural lord of the 1st and Mercury lord of Virgo upon your Ascendant Mercury as lord. (Does Mercury make a parallel with any of these 7th house lords?)
An aside briefly here: Would you be talking of a relationship of a live in nature as you had mentioned or the legal communion? Moon is lord of the 11th house of hopes-(with Saturn lord of Aquarius/Capricorn) wishes, the sign of Cancer being there her sign host; which she lords over. The implication is that you wish to include a dwelling as cementing a unionizing agreement, Moon moving to conjunct Saturn for that togetherness with the paramour is angularly (4th house with Sag. on the cusp=common sign/changeable/movable) coming about soon. The Moon in a changeable sign expect many emotional ups and downs in agreements to these things.
The measure of time could be 12 weeks as a commitment timing with a prior love interest as Saturn is lord of the 5th (older or prior steadfast love interest) with the Sun host lord of Leo whom naturally owns the realm of the 5th..a romantic interest forms before the 7th union comes into interplay..the legal promise.(Don't like the Sun moving to a square with Saturn, his masculine influence or identity is experiencing an obstacle=some conflict within these areas of topic..marriage..romance.)
The Moon gives rulings of dwellings and removals to a different home life-she will make a conj. with Saturn the lord of property and removals of hearth. She has meaningfulness stemming from the 4th in these matters.
About the topic of marriage-Jupiter describes an attitude which needs to be forthcoming for the commitment of unionizing can take place, he is not a fast moving planet making contact with Saturn as the last Lilly planet to be used in his acceptable powers giving mention of events and activities. Jupiter is moving away from the flowing sextile with the interest that is solid, and will meet with the 8th (changes for solvency reasons?) house Hershel (Modern=sudden removals or ties being broken, the separation aspect opposition as the force behind the energy) with Mars deposited within as main forces that play an important role in your personal makeup..resources and physical attraction.
Mars (host lord of your Asc.) moving to the aspect of separation to Jupiter (7th Pisces sign lord as well as being lord depositor of Saturn in the 4th, lord of the sign of Capricorn on the 5th, destiny of the romance?) is moving to conjunct Hershel to make the opposition to Jupiter/retrograde (agreement of moving to meet the separation with Hershel) additionally Mars is a force there (as mentioned above host Asc. lord) an eminent energy that is significant of you making a decisive call in these areas..adamant to separate unless commitment to solidify the union is brought forth under some agreement is made in these areas?
Thinking there will be some changes made in these areas (Venus in 8th of changes/transforming house) as Venus is in mutual agreement with the Sun in the future 6th/health of the romance (Sun is host lord of the romance 5th..significant of male energies also identity-pride) She (Venus) will be in exalted Pisces in his future (5th is the romantic Saturn partner) and he (Sun) will be exalted in dignity by her in agreement to make these decisions with acquiescence or admonishment by him..some compromise? As I see it money resources and physical attraction play a very important role in whether or not there will be a common law commitment or not in the coming weeks = months. But I do see 12 weeks (Moon in common sign Sag. on angle = weeks) as an increment of timing in the context of your question..as the other's have seen.
All the best

P.S. The opposition could mean temper's flaring about these issues which could go either way in your favor, as to moving suddenly or of a sudden separation you make from masculine energies altogether!
Am additionally concerned bc I don't see Venus host of Libra (where Via Combustion legal unionizing Jupiter tenants=sign Pisces on 7th marriage coming) in a favorable movement to Mars. She will not meet up with Mars=marriage. Mercury is combust also (much talk without solid agreement being met?) Sun is moving away from the combustion but is still overshadowing your Virgo/Ascendant sign, Sun having more power over these decision of moving?
Take care
Wishing you a solid decision in your favor...do you have a prior gent in mind? Just curious.
