Not feeling dragon wifey At all. At least glasses loves him for who he is and what he did. Dragon likes him because he was literally the first person she saw spending time with their family, could've been anyone.
@darkcat28 nah ur assuming that the growth happens at a flat ration compared to human growth, its very possible that they grow quickly until they reach a level that allows for basic autonomy and then have slowed growth after
As the cat said, fuck them both, dragon girl will outlive you by a lot of years, the kids wouldn't even be teenagers by the time you die. A human partner alongside the dragon is best option here.
