I don't know what to do

I love my boyfriend and he says he loves me but if I don't see him 20-25 hours a week then he gets so unhappy. Because I can't spend the night as his house, he says that we are not in a "real relationship". I thought we were serious, he's met my parents and he tells me that he even wants to marry me one day but I'm always afraid that if I don't fulfill his requirements then he'll leave me. If the circumstances aren't good enough for him, he said he might have to leave me. I don't know what to do or how to cope with this.
