Relationship advice

Looking for some advice.. my husband has become such an angry person lately and I know a lot of it has to do with his family, because they don't see eye to eye. I've done everything to try to put him in a happy mood, but everytime he's around his family he becomes angry and yells a lot. I've tried to encourage him to remove himself from the situation, but he really can't because they have a family business together. I feel like it's starting to take a toll on our relationship and I feel like it brings me down too. I ask for a little help every now and then and when I do he gets all mad and storms away. I feel like I'm trying to do everything by myself and he expects the house to perfect, but it's so hard to do when I work all day and then come home to help him with his chores and cook supper. Some nights we don't get done with supper till 9 p.m. and I'm exhausted and ready to call it a day so I can repeat it all over again the next day. I've become emotionally and physically drained. Any advice would be appreciated! Thanks!
