Is he turning me off?

Me and my boyfriend haven’t had sex in a little over two weeks, it may not be that long but for us it is… a few days ago he mentioned to me that I haven’t been wanting to and that we haven’t done it in a while, i agreed but i also told him it’s just my mood because not only am i PMSing but between arguments and having to go to work and then coming home and having to clean and make food and then take care of myself, even though it seems normal, it still is a lot of work that by the end of the night the last thing in my mind is sex. I wish I wanted to in this moment but I just cannot get in the mood, he’ll see me in a pissy mood when I get home, but what he doesn’t see is the clothes all over the place, the dishes in the sink, the food that needs to get made, the drink that just spilt on the floor, and the bathrooms a mess.  if anyone has gone through anything similar, how did you explain to your boyfriend/husband what was going on in your head and the reasoning behind not wanting to do it but also what did you tell them to get them to also help you out and to understand your emotions ?
