Feel like breaking

I feel like breaking, I have two children one a newborn, I have a partner, who works 8-5, I'm on maternity leave from work, I am feeling down and fed up. I do everything and I mean everything, 7 days a week 24/7, cooking,cleaning, school run, caring for the kids, caring for him, doing all the feed even the night feeds, he probably done 10 feeds in 3 months, he gets lay ins, he gets him time, get to sit and play the Xbox or go football etc, i have a warm/ cold meal, apart from Sunday my mother in law had my baby, we were out for a meal and I went to take her so she could eat her food, I nearly cried when she said no you eat your dinner when was the last time you had a hot meal, I said I haven't. I just start doing a class to get fit for an hour in the evening, but I have still done everything for the kids before I go, I don't get to nap, don't get a lay in, don't get me time to just unwind, I've raised it with him and he goes on about him working etc, he goes on about how I say I want a family yet don't do anything and the kids are just trophies like the dogs are trophies, their there because it's what normal, I sit and play with the baby, I sit and have cuddles with my kids, read stories, tickle time and yes I haven't done much with our eldest as I have to tend to our newborn and I'mentally and physically exhausted, I take them out wherever I go, I go to play areas with friends and I go to play groups with my baby, I get told I'm selfish and self centred because all I care about are my feelings and how I feel. Am I selfish for wanting to be able to have a nap or a lay in once in a while,or a meal cooked for me or to be able to have an evening to pamper myaelf for an hour or just me time with no kids am I wrong for that? Does that make me a bad mum? I carry on doing every because I feel guilty and awful for it so I don't I carry on doing everything, which I did when I was working and heavily pregnant. I'm getting fit and doing what I can where I can for myself because he isn't picking me up, I don't get told I'm beautiful or im doing a great job, it affects me mentally as I start thinking what am I doing so wrong and I'm an unfit mother because I don't do enough for my kids,I just want to cry . My kids are my world.
