Live-ins, also known as cohabitants, refer to individuals who live together in a long-term committed relationship but are not married. Alternatively, antonyms for the word live-ins may include single, alone, solo, individual or separated, among others. These words denote a state of being or living alone, without any prolonged companionship. While living alone or independently may offer freedom and independence, it can also lead to feelings of loneliness and isolation. On the other hand, living with a long-term partner can provide companionship, emotional support, and added security. Ultimately, the choice of living arrangement depends on an individual's personal preference and life goals.
