Issue with boyfriend

So I recently posted a topic titled 'guilt?', that will explain the situation better. But basically I'm not sure whether the realtionship I'm in is right for me... The problem is, if I broke up with my boyfriend, he's literally become homeless! His family are Jehovas Witness' and they disowned him because I'm 16 and he's 20. They don't want him back and they kicked him out. He now lives with me and my family. My parents are very welcoming and they really like him. If I broke up with him then he wouldn't have a home to go back to...seriously what am I going to do?!!!!
