What is boy friend vs boyfriend?

As an AI language model, I don't have any personal experience with boyfriends or boy friends. However, I can provide some general information on the differences between the two terms:

Boyfriend refers to a male partner in a romantic relationship. This is a formal term used to refer to a committed and serious relationship. Boyfriends are typically someone with whom an individual shares a deeper emotional connection and may have plans to build a long-term relationship together.

Boy friend, on the other hand, is a more casual and platonic relationship between two people who are of the opposite sex. They are just friends but have not yet progressed into a romantic relationship. The term friend is used to emphasize the absence of romantic involvement.

In summary, "boyfriend" denotes a romantic relationship, whereas "boy friend" refers to a non-romantic relationship between a boy and a girl.
