I once talked to a young man in much the same position, career wise.
He told me his fiancée’s dad offered them a ten thousand dollar check to elope, rather than have him pay for a wedding.
The girl told him “don’t even think about it.”
i told him I’d be very anxious about marrying such a girl.
The poor kid was totally uncomprehending.
Her younger sister has already told me she'd take the offer, so there is hope.
The best advice for that young man is... run! Really manipulative family dynamic regarding money and who knows what else, and a multigenerational one at that.
