Did he have a round-trip ticket? A requirement for the VWP (90-day visa-free stay in the USA) is proof of a round-trip ticket. He can be denied for as little as that. It's a huge privilege and one that comes with many strict conditions. As you are discovering.
So, have I understood this correctly? You have never met in person but you were planning to marry and he was planning to stay here? He left his job and everything for a woman he's never met? There's a reason why K-1 applicants have to provide proof of having met in person. To immigration this looks like he just wants a green card.
Slow down. You're both very young. Spend time getting to know one another. Meet in Canada or somewhere in Europe. Enjoy your youth and see the world in the process! If you are meant to be together and if you are truly in love then the love will last until the time is right.
You both made a bad move here. Stick around here and learn how to do it the right way and also get a better understanding of the huge emotional journey that international marriage is. It's not for the faint-hearted.
