So unhappy

I am just not myself anymore. My partner of 8 years is the most selfish man. He goes away next week for a full 7 days. Monday to Monday. Leaving me with 2 year old and 3 month old. Told me this morning he won't be around tomorrow because the boxing is on so the kids won't actually see him until Sunday. But he just expects me to do EVERYTHING. It's like he still has his life and I'm stuck at home with 2 kids. I have no family around and no friends either. I have zero village. It's like he makes plans and doesn't think about the kids. He's just come in from work and I'm literally sat on the floor sorting washing out. I get a 'what you doing'? Well what does it look like I'm doing. I didn't fold any of his stuff cause I was mad so he asked why. I said when was the last time you did anything for me? He leaves me with all washing, cleaning, food shopping and just expects his uniform to be ready for work or his jeans be washed ready for his day off. He actually does NOTHING for me. All the washing piles up on the table as he puts another wash on cause he needs something of his washing. Not cause he wants to help. I am just absolutely miserable. Crying constantly. Jealous of everyone who have decent men. 😭😭😭
