This seems like an Inverse = true problem. You should be able to delete a child without affecting the parent. Your collection should have this attribute:
[HasMany(Inverse = true)] This makes the child responsible for persisting and updating itself, not the parent. Thus, you can delete children without touching the parent. Keep in mind though that if you do use Inverse = true, you'll have to set the child's parent as well, or else it'll save a null value in the database for the parent ID. If you just want to use collection.Add(child) without also using child.Parent = parent, then you can't use the inverse. Come to think of it, once the parent object gets saved, doesn't it become persistent? The parent should know how to delete itself once you save it.
