moving out advice?

Anon
I'm 18 and here soon I will be moving in with my boyfriend. More than likely he will have nothing to his name due to his relationship with me and his mother. (Because he is with me, and has been for bearly 3 years, his mother thinks he is choosing me over her even though he spends all his time with her). What are some things for our new apartment that we will need, strage ideas, etc. any advice is welcome!
