Bismillahir Rahmanir Rahim.
As a temporary arrangement this would be fine. However, as it is wajib for the husband to provide a home and maintenance for his wife, you would need to find alternative accommodation as soon as you are able to do so. This should be sooner, rather than later. It is more preferable for a man to be able to be financially sound before he enters into a marriage, than to go in incapable of providing for his wife.
And Allah(swt) alone knows best.
