I am so f#%king angry right now!

Katie
I have been with my partner 6 years and he has always been useless around the house never once has he washed up or helped with anything. We have a 6 month old son and I'm 3 months pregnant with terrible sickness. My mum is babysitting my son tomorro for the first time so that I can get on top of all my house work as Iv been struggling lately. I just said to my partner that I was him to clear the garden of dog poo and clean the windows. He looked at me in horror and said if I do it once you will want me to do it all the time. 
I do everything, every single thing I don't get to rest until gone 10 every night and then I'm up loads with our son I'm fucking shattered and I just want my house to feel clean and tidy.he works part time and does nothing when he is not working. Are relationship is failing massively because of how lazy he is and he is pissed at me for expecting a little bit of help. I'm so angry I want to tell him to get the fuck out of our house if he can't pull his weight but at the same time I do love him.. ahhh I'm so angry 😡
