How to heal my Rage…. I want to leave my baby daddy so bad.

I clean after my baby, I clean after me. I clean after my baby daddy. I work. I barely have time for self care & im deteriorating & exhausted. I have built up rage. I repeat myself constantly during my day……….. It’d be fine if it were just to my toddler son. But it’s also to my partner. If I even feel like considering him that. He doesn’t meet my needs. I’m honest and transparent about this. I repeat myself on STUPID basic hygiene stuff around the house. He makes my life feel harder because he’s immature & childish & boyish. He can’t flush the toilet, he can’t pick up his trash, he can’t pick up his clothes, he can’t wipe down a counter, or anything. He is helpless around the house & his cleanliness is disgusting. He doesn’t even wash his hands after a shit then wants to touch up on me. I already had previous built up rage about him. Due to our past. He’s a great dad I love him you know. I can see him underneath the version of him that can’t seem to give a s*** about my needs & how it affect my mental health. He mocks me, or replies only sassy about my concerns. I feel defeated and hopeless. My rage is so bad that my health is AWFUL. Just stress induced. I don’t know now, if i’ll have more peace & he’ll learn if i’m silent & just continue to pick up after him. I mean he SEES the condition i’m in you know? disgusting, highly depressed angry and anxious. Consumed. I can’t find peace. I literally can’t because he fuels me so negatively. I want him to grow up SO BAD. I told him last night I’m done being his parent. I still have to remind him over and over and over and over and over wasting my breath, deteriorating my health and sanity. I’m so beyond frustrated and disgusted. I feel so unholy in this position. I want to feel holy. I want to be happy, I want him to back me up & help ease my pain. But he is the reason i’m so i’ll, mentally & physically. He’s just not good right now & I know this isn’t the version of him he even wants to be, he just has demons, as do I. I’m suffering SUFFERING. I think we will break up soon but I have no freaking clue my path outside of the routine where he can support overhead of majority of the bills, & I get a life where I can be with my baby. If he’d just grow up I could be healthy.
