Dear Annie: I have been married to Sarah for nine years. We have two young sons, both with developmental problems.
When I met Sarah, she had an older son, “Del,” who was in the temporary custody of her father's cousins. The cousins have raised the boy since he was 6 months old. He is now 13 and understands that our sons are his half-brothers. His biological father gets him on occasional weekends, and he always has had regular contact with Sarah and her parents.
