<human>: Condense the text into a few key points

I go to an out of state university, and I was recently studying abroad in Japan. While I was gone (three weeks ago, about), my family acquired a Brazilian exchange student. His old host family was having some family issues, so he needed to move to a different home. My bro (15) volunteered, thinking it'd be fun, plus it'd be nice, whatever. 

He is so, so sweet. Really. Like, one of the nicest guys I've ever met. But he needs some serious help. He is always asking for help with the dumbest things (he asked me to help him peel a sticker, once), he is very physical with everybody (my family is very uncomfortable with physical contact), and constantly needs to be interacting with other people (my family needs their quiet time every once in a while). He is also weirdly competitive, and whenever we play games together as a family, he gets very upset when he loses. On top of it all, he is barely passing any of his classes in school, and may be returned to his home country because of it. My mom is a nurse, who often works with students who have special needs, and she believes that he has Asperger's and just hasn't been diagnosed. 

I know my family should have taken this into account when getting an exchange student, but he really needed a place to stay, and was quite desperate. He's an only child at home, with a stay at home mom, so he's probably used to a bit more attention. However, he doesn't meld very well at all with our family. They haven't said anything about any problems to me, but it's very, very apparent that his presence is very taxing for them. 

For now, while I'm on break, I will do my best to occupy him, and make sure that my family can have a little reprieve. They have to deal with him for the next 6 months. There needs to be some sort of long term fix, though, where my family doesn't go crazy, and he doesn't get his feelings hurt by getting kicked out of another host family. 

Thanks for your help!
<bot>: Family volunteered to host an exchange student, turned out he is very immature, dependent, and a bit bothersome. Need some help resolving the issue before I go back to school.
