Yeah, the no-sleepovers bit is something I would imagine is likely the case for any teen couple. but that she wouldn't let them "hang out as much" is worrying.

Also, idk, might be worth talking to the daughter about sex & serious relationships and so on... to kind of counter the ex-husband's somewhat dismissive view (I get that he probably means, no one's getting pregnant but... idk, why not just say that? It sets up some concerns... and makes me think they don't have good sex ed).
