Chapter 62 A LIGHT SHINES ON MY WAY

.................................
The year came round to Christmas-time, and I had been at home above two months. I had seen Agnes frequently. However loud the general voice might be in giving me encouragement, and however fervent the emotions and endeavours to which it roused me, I heard her lightest word of praise as I heard nothing else.
At least once a week, and sometimes oftener, I rode over there, and passed the evening. I usually rode back at night; for the old unhappy sense was always hovering about me now - most sorrowfully when I left her - and I was glad to be up and out, rather than wandering over the past in weary wakefulness or miserable dreams. I wore away the longest part of many wild sad nights, in those rides; reviving, as I went, the thoughts that had occupied me in my long absence.

Or, if I were to say rather that I listened to the echoes of those thoughts, I should better express the truth. They spoke to me from afar off. I had put them at a distance, and accepted my inevitable place.

1. I'd like to if "as I heard nothing else" is the objective complement of "heard."
2. I'd like to know what "be up and out" means.
3. And I'd like to know what "were to" means here.
Thank you in advance for your help.
