The applying trine is favorable,
I would look to reception from partner/Moon to Saturn, though, to fully answer this question. There is no reception, favorable or unfavorable, which likely provokes querent's question in the first place?
Querent receives Moon by triplicity, so not the greatest love story in the querent's heart, but certainly there is appreciation for the other. I really don't see feelings reciprocated to the same degree by the partner.
However, it is notable that querent is in the partner's 7th, so is seen as a partner. While partner is in querent's 5th house of romance. So maybe querent is seeking romantic actions as expressions of "love," while partner actually holds querent in a more grounded, lasting [hence the trine] and matured way?
