he's moving back home

So on Sunday my boyfriend is moving back home and I do not know how to cope. I can already feel the anxiety. His mom kicked him out so my parents welcomed him with us. His mom hates me and she's told him who told me. He gets annoyed with my family because my mom and one of my brothers drive him insane. I would mention moving with him to his home but again, his mom hates me and told my dad I was never welcomed to stay at their house. I love him so much and we have been dating for almost a year now and we hit it off at the start. I understand him moving home because he wants to see his family more but he never made an effort to see them until now. He told me he wanted to move out almost a month ago, and last week said his mom is looking to get him a new bed and he'll move when she gets it... and she's getting it tomorrow. We are both seniors in highschool and he has told me his education is priority over me... when him AND my education are my priority. I told him how I felt when it first came up but I feel guilty for wanting him to stay. I don't know what to do... I fear his mom will manipulate him to leave me because she told him to keep his options open.
