Yes, it is *a* factor, in the sense that people's emotions change and can fade over time, in the same way memories do (since they're often one and the same, within the workings of our brains). What I was getting at was the fact, that you could have lost your wife/husband/partner/lover years ago, but so long as emotionally you still have the same feelings for them or your memory/attachment of them, they might be strong enough to still protect you. Possibly strong enough to leave a sufficient imprint on meaningful items even, such as the wedding ring, so long as you still interact with those items daily while feeling those emotions, in essence the exact same principle as enchanting something and refueling it over time.
