"My Girlfriend Said She Can't Marry Me Because I Stay In Selfcon Apartment"

I work and trade crypto and forex, my girlfriend knows how much i earn, but because i have plans, i still live in a modern selfcon in an estate.

So tonight i asked my girlfriend whom i wish to marry, if she would be willing to marry me as i stay in this selfcon, even if i don't have money to rent 1bed room.

She said she can't, please what does this mean? Possibly not my class? Possibly might leave when things go bad?
