Feeling defeated

My SO lost his job and is desperately trying to find another. He’s applied everywhere and went to a job fair at a local store yesterday. Nothing. We were depending on my car after his truck got hit and we couldn’t afford another. And now mine is broken down so we’re out a vehicle until it’s fixed. We’re living with my mother until we get into our apartment and she’s being really hard on him about a job and he’s trying really hard. She just thinks no one is good enough for her kids and that’s not fair. She’s one of those people against marriage and living with men (she’s crazy). I’m so stressed and don’t know what to do. Any advice? 🤰🏻
