I don’t think she has any intention on bringing her kids. She didn’t seem to be that close to them anyway. If anything she should just send more money back to them so they can attend the best private schools and universities there. That would give them more opportunities than the lower middle class life they’d have in Michigan.
I think that’s unfair. The woman was clearly looking for a sperm donor and picked a young, healthy looking guy in a foreign country who didn’t have kids as part of his short term plan. She let him know out of courtesy not because she wanted him to be part of the kid’s life.
