I'm 17 and my bf is moving in

Shayla • Mommy to 2 angels 👼 •Mommy to Myah 🌈 👑 👶 Divorced once. Happy Again 👨‍👩‍👧
My bf is 19 and I am 17. He is a senior this year and is 2 weeks away from graduating. A few days ago his step father came home and announced that he'd been having an affair and wants a divorce. He then proceeded to kick his wife and her children out. Because of the abusive behavior that had been going on my bf's mom and sister are in a safe house. My bf is living with the neighbors until he graduates. Once he graduates my parents have asked him to move in until he ships out for AIT (Military trainining). I leave for basic 2 weeks after he moves in so we won't be living together too long. I'm just worried because we're both so young and only been dating for 2 months. I guess if God gave us this trial it's meant to make our relationship even stronger. Anyone have any advice for us?
