I need help

Would you stay with someone like this for the sake of your 3 year old and 5 month old? I've never wanted to unalive myself so badly.

Fight started when i said the baby went to sleep late last night around 11 and i said he told us he was tired because he was crying a whole bunch.

He started yelling at me demanding an apology for disrupting his life on purpose. That I'm always doing things like this on purpose. He called me a narcissist for never apologizing and that i should just leave and never come back. That im disgusting for how i never apologize. At the time he was demanding an apology and i had no idea what even for?? After finding out i did apologize and said how's that any different then from how you wont flush your poop. You literally said you left it to spite me. He said he was "joking" and that a MINOR issue like that isn't even comparable. Even though we have had countless arguments and fights about him not flushing his disgusting poop FOR OVER A YEAR. Which had been in the bathroom ALL day again. He went on to say it was super easy to flush it and that i was making a big deal out of nothing. I said if it's so easy then why can't you do it? Then he said i was disgusting for how i left the house when i went to go visit my parents for 3.5 days. Because i left a half eaten lasagna on the stove (that could have just been thrown away how it was if he didnt want anymore) and left the trash in the trash can because the garbage can was full because i missed the trash guys by literally seconds that past monday. That I can't do anything. Can't get a job (even though im literally in the process of getting a government job that pays 30/hr. He. Kept saying I couldn't even call the daycare(which i did) and was trying to force him to call (which i wasnt). When all i did was say you could stop by and tell them the kids won't be there until Thursday since it's on his way home and he hasn't seen it yet. Then he started on about when did you study!? Did you study any even?! Because you're a failure! You failed your test! I asked him to stop calling me a failure because i was obviously in tears at this point and he said F-A-I-L-U-R-E, that's what you are!! I was crying and then he said right because I'm the mean one now right? I'm the gas lighter whose yelling at you. No im sick of you gas lighting me!! You need to just get up and leave. Youre always acting like you're under so much stress and have so much going on. Said i got pregnant on my own and did it to myself. Held it against me that i was in class and not working last year. lThat I'm a pos for staying an extra day with my family. When i visited.
