Will a man be willing to be a door-to-door son-in-law (I hope you handsome guys can talk about your thoughts)

Subjectively, it won't, but some men compromise for their own abilities and other factors. It is also possible that the man will consider the woman's special situation, such as the girlfriend's parents need to be taken care of, and will also accept adoption, but we should not discriminate, many things have internal causal relationships. However, the woman had better not insist, let alone be overbearing, otherwise it would be a tragedy at least emotionally.
