So me and my girlfriend decided to move into together after dating for 3 years. It's been 2 months and I've noticed here attitude towards me has been completely different since moving in together. I work 80hr weeks at my work on top of driving everywhere for everything we need since she doesn't have her license. I come home and I'm always doing the housework when not needing to run to the grocery store or other places that come up. I do the dishes, trash, lawn care, take care of our pets, pay the bills, everything there. When I bring it up she shuts down, says it's because her mom always made here do everything growing up. I get that because my mom was the same way but idk how long I can keep this pace up. Im run down physically from work and mentally from trying to figure out how to get her to help me around the house. I don't mind helping out but damn I can't do it all by myself day after day. Any suggestions are appreciated. 

So my father in law hasn't been doing well. He is about to have a major sugery soon and my sister in law took it upon herself to say I'm coming to visit for a week straight. Im staying at my in-laws during this time (which is four states away from my home) because my mother in-law is in a nursing home and cant care for herself so my father in-law would be on his own post surgery.. The only problems is that she is highly racist and homophobic. It really bothers me and I don't want to associate with that. I'm thinking about just staying at a hotel the week she comes to visit. What's your opinion on this?
