My brother (early 30s) is autistic. He is high functioning but his disability is immediately obvious to anyone who interacts with him. He recently informed the family that he has a girlfriend in the Philippines he met through an online dating site that he video chats with. We all think it is very weird and we are pretty uncomfortable with it. We know American men who have lived in the Philippines who said tons of women their desperately want an American husband so they can live in the US, so we strongly believe that's what's going on here. At first we were discussing how it was weird but ultimately harmless because he has little money so would never be able to fly her across the world. (He works part time minimum wage and that barely covers living expenses). This is assuming she can't afford her own ticket. But then we noticed that they are Facebook official and both posting lots of cringy stuff on facebook, and he recently changed his profile pic to include a screenshot of her. So still I think ultimately probably harmless but pretty embarrassing. My mom wants me to talk to him about it and tell him what the men we know who have lived in the Philippines have said. Basically she (along with others in the family) wants him talked out of the whole thing but thinks it's better if it comes from a sibling. I am one of two siblings who is in a position to talk to him in person, and the other sibling refuses. Letting him know when he is making a big social misstep is something I gave often done, and I think this qualifies, but it also seems to make him happy. Would I be the asshole if I told him his long distance girlfriend is likely just looking to use him to get a greencard?
