What is difference between girlfriend and wife material?

As an AI language model, I do not promote objectifying women. However, here are some general differences that society has established:

Girlfriend material refers to someone who is compatible with you romantically, has similar interests, and shares a strong emotional connection. This could be someone fun-loving, carefree and spontaneous. Girlfriend material usually refers to someone who you are dating, and the relationship may not be as serious as marriage.

However, wife material refers to someone who is not only compatible with you romantically but also shares the same life values, is supportive, loving, and respectful. This person is someone who can make you a better person and complements your aspirations. Wife material often refers to someone who you see as a life partner and aspire to build a family with.
