Why can't I get a break

So My sister is cooking dinner to right as she's staying at my house and thinks she needs help cooking this is the second time she has cooked sense staying and here and asked for help then. I told what do do last time but she dosent listen to me. On too of that my husband was being a jerk. He gave me 5 to get potatoes and asked me to get water I got the potatoes but not the water cause I couldn't afford both. I had 3 left in change and 2 at house he gave me a few day earlier. I was going to get me a treat but no he freaks out on me and I went and got his water. I'm still pissed. Oh and I don't get help with our house chores or my truck besides gas. I don't know what to do anymore because talking to him dosent help at all. He's great with the kids and he loves me but is lazy when he gets home from work. His stupid dad thought him that's it's the women's job to do everything with house and it's pissed me off tbat he thinks it's ok to still do now that he's married.
