Azi, the point is BMG is trying to run a yeshiva. They don’t appreciate boys enrolling and then starting a shidduch right away- killing the whole first zman in yeshiva for him and his chavrusa before he even got a chance to settle and leaving yeshiva as soon as he finds his shidduch. They don’t want to be used.
If you want to date you can find yourself a place to stay anywhere in the tri-state area and learn in any beis medrash you want. Just don’t enroll in BMG.
They’re not forcing you not to get married. Just go one zman before you plan on dating.
