The term "life partner" is a broad and inclusive term that refers to an individual with whom someone has chosen to share their life, often in a long-term committed relationship. This person can be a romantic or sexual partner, but it doesn't have to be limited to those definitions. A life partner could also refer to a close friend or family member who plays an important role in the other person’s life and shares responsibilities with them. The term is often used interchangeably with terms such as "significant other," "companion" or "partner." Ultimately, it refers to someone who is deeply connected to another person on a personal level and plays an important role in their life.
