One person added a valuable piece of advice, saying that if the OP had children or anyone reading had children, they should have a will saying who would take guardianship of their children when they died.
Another person shared their experience, saying after their parents had died, their half-sister took them in, and it was apparent they weren’t wanted there.
The person then ran away when they were 15, and neither their half-sister nor her husband reported it.
This commenter said it had worked out best that the OP and his wife split because his sister would pick up on it if she weren’t welcome.
Another person who did not have children said it would have been a dealbreaker even for them.
Some people came to the OP’s wife’s defense, saying she knew her limits and could not care for a child dealing with such immense trauma.
Another said the OP’s wife did not want to be a mother, and raising his sister would essentially place her in the position to be one.
Another person said they would ordinarily side with the wife, but because she had been immature in saying the OP was picking his sister over her, they didn’t feel it was fair on the OP and his sister.
