Based on the writings of Ellen White, here are the answers to your questions.
### Separation from James White
The available writings do not indicate that Ellen and James White ever had a marital separation. Their life was characterized by a shared ministry and extensive travel, which sometimes kept them in different places for their work. They were married on August 30, 1846, and she wrote,
"Our hearts were united in the great work, and together we traveled and labored for the salvation of souls" (1T 75) ⚠️ Reference could not be verified.
Their time apart was due to ministry and health reasons, not a marital split. For instance, one passage notes, "James White's own failing health, his conviction that others should be stepping in to lift the burdens, and his frequent calls to duty elsewhere, all tended to separate him from the administrative interests at Battle Creek" (
3T 3.3). They remained married and worked together until his death in 1881.
### Care of Their Children
Yes, due to their extensive travel and ministry commitments, their children were often cared for by others. Ellen White described this as a significant personal sacrifice. She wrote:
"Although the cares that came upon us in connection with the publishing work and other branches of the cause involved much perplexity, the greatest sacrifice which I was called to make in connection with the work was to leave my children frequently to the care of others" (LS 165) ⚠️ Reference could not be verified.
