My husband doesn’t want to move out of my parents house

A couple months ago some stuff happened and my husband ended up loosing his job, we lost our car everything. we had to move back home and ended up staying with my parents, well that was 4 months a go, we both have a job now, and can more than afford to get into our own place but he gets pissy every time I bring it up, tonight we got into a fight because I found this 2 bedroom house just down the road and it’s only 500 a month with utilities paid and it’s not even a block away, well my sister and my husband and I are sharing a car my dad gave us, she already told us we could take it when we get a place if we will just pick her up when I go to work (we work at the same place, and same schedule) because she is going to be putting a down payment on a new car with her next check okay no problem Well when I told my husband about the house he got mad saying he didn’t want to have to depend on people because we wouldn’t have a vehicle, well when I told him I ha already talked to my sister about it and she said we could take the car he got even more mad that I talked to her about it first. I just don’t know what to do because he says he doesn’t want to keep depending on people but, aren’t we depending on people now, living with my parents? It’s just frustrating because I feel like we’re never gonna get into our own place. What should I do?
