I get treated better at work than at home

My coworkers say that they enjoy working with me. People will call and ask to speak to me to help them because they know I will be kind and get the job done. I get praised for my efforts. I actually look forward to going to work because it's an escape from my home life. My SO is a miserable, bitter person and he criticizes everything that I do. Nothing I do is to his standards. He is impossible to please. Even after sex he blames me for him not lasting long (which I don't even care about). When I cook, something is always wrong with it. He finds a way to critique it without my asking. When I clean, he finds things that I miss or he redoes things because it's not up to his standards. I am so tired. So warn down. I know I am not perfect but I am so tired of being constantly put down in my own home. My only joys in life are sleeping, my pets and work. I am a shell of the person who I was before I moved in with him. I am just realizing how lost I am. How I miss someone complimenting my looks, enjoying my food without criticizing it, someone touching my hair or my feet. Having Sex and actually feeling safe and comfortable with that person. It sucks because overall, I always seen the good in situations, I am not sure how me being a big optimist attracted such a pessimist. It sucks that people who I hardly know, treat me better and more human than someone who claims to love me the most. thanks for listening
