Why would someone say after first date that they’re looking for their soulmate and a good wife?

There’s no one answer to this question, as it can depend on a person’s individual circumstances and feelings. Some people might say that they’re looking for someone who shares their same values and interests, or someone who will make them happy. Others might say that they’re looking for someone who can share their life with and be a good wife to them. Ultimately, this is a question that each person must answer for themselves.
