Every bit as strange as it sounds. My brother is in his mid-twenties, and I recently found out that the long-distance "girlfriend" that he's been mentioning in passing for a few months now is, in fact, a model on a popular cam site. A model that he hasn't spent an obscene amount of money on gifts for. A model that lives half-way around the world. 

The dude's totally over the moon for this lady, obviously, but when he revealed this information I (OK, maybe not so politely) expressed my opinion that, in all probability, she views him as a particularly attached client and will take the shirt off his back before they ever meet up in person.  

For his side of things, they do text a shit ton via kik, and exchange sincere-sounding words of affection and everything. But the financial component makes me think this is patronage, not a real relationship, and he's gotten things confused. Obviously he has not taken this well. And I have entertained the idea that I may be just the world's biggest asshole for saying so, love conquers all, etc. But I am in fact worried about the guy. AITA?
