Question about renting in Virginia?

My husband and I just moved into a place on Wednesday. Because of our situation, they agreed to let us move in and pay next week when my husband gets paid. I attended orientation for a new job yesterday, where they informed us we wouldn't get our first check until May 3rd. The guy agreed we could pay him $250 every two weeks for rent. He asked about the deposit and told us it didn't have to be paid all at once. When I got out of orientation I text him and told him about not getting my first check until May and that I would give him the deposit then. I also stated that if it wasn't enough to cover it all I would pay him the other part on my next check. I thought this was fine as I did not receive a text back saying otherwise. Now, at 3am I get numerous texts from his girlfriend saying the living situation is not working, that we argue and slam doors (which is not true). She also said they couldn't wait until May for the deposit and that they talked to their landlord about us moving in and he doesn't like it and that we need to be out by Sunday at noon. I have a friend saying that regardless of the money situation they have to give us 30 days to move. What can I do?
