Your Natal 7th brought to the 1st house in your SR chart certainly adds more weight to the partnership theme of your SR chart. It would seem likely that something significant might transpire in your relationship this year that will be directing your focus to it. I would look at the 12 Lunar Return charts for the upcoming Solar year so that you can identify the month(s) where there will be the most pertinent activity related to this overall theme of the year. The LR chart that most closely resembles the SR chart (whether by aspects, configurations, same sign rising, etc.) would be a month that might find the most obvious manifestation of the SR potential. I've also read that if you have a Cardinal sign rising (e.g., Capricorn) in your SR chart, then you should look to the first four months of the Solar year for the bulk of the activity (a Fixed sign rising would relate to the middle of the SR year, and Mutable the final four months), but I'm sure there are divergent schools of thought about that.
I can't emphasize enough the importance of bringing it all back to your natal chart. Are there any planets or angles in your SR chart that conjunct natal planets or angles? If possible, definitely post your natal chart as well because that's the highly important missing link and since your discussing the possibility of marriage, this also relates to synastry and how compatible you and your partner really are.
I'm probably not the sharpest chart delineator on this site, so perhaps someone else might give it a whirl and be able to synthesize it all with greater precision.
