1. To continue to be physically present alongside someone or something. I want at least two armed guards to remain with the prisoner at all times, do you understand? John decided to remain with the truck while I went off in search of help.

2. To continue to be a member of a group, team, organization, company, etc. The star quarterback could sign with any team in the country, but he decided to remain with his home team in Denver. She said she would remain with the company for at least another year.

3. To continue to be in a romantic relationship with someone. I don't understand why she would remain with a jerk like him. I know my dad remained with my mom out of a misplaced sense of propriety and duty, not because he loved her.
