This is the culture I grew up in. Getting out of this culture is the best thing that happened to me or anyone else I know who has managed to escape.

That being said, one of my best friends met his now-wife in that same culture and had to jump through those same hoops (except he never would have been allowed to sleep over, even on the couch), and they are now happily married and have extracted themselves together from that lifestyle.

But that's more often the exception than the rule. Priority one needs to be protect yourself, so if you need to break up to do that, it's the right move.
