Starting to feel like a single mom in a relationship.

I’m so frustrated right now I could cry. I literally have not slept in over 24 hours. I’m starting to wonder why I’m even still with my children’s father because the longer we’re together the less he does. He works during the week so I get up with the baby at night. She’s currently teething and going through a sleep regression at the same time so she’s not been sleeping hardly at all lately and I can’t nap during the day when she naps because we also have a crazy toddler who wakes up at the crack of dawn and does not nap during the day. Last night the baby would nottt go to sleep. She fought her sleep from 10pm until 3am straight then every time she’d fall asleep, as SOON as I would close my eyes she’d start screaming again. I didn’t get her down in a good sleep until 6:30am and by that point the sun was rising and our toddler woke up for the day so I had to get right back up with him meaning I got absolutely zero sleep last night. I was too tired to do much cleaning today so when my bf got off work I asked him if he would help me pick up the toys all over the house and put them back in the play room and straighten up a bit. He literally scoffed and said “I’m not doing that I worked all day I’m too tired” and walked off to go watch tv….. like at what point am I allowed to say IM too tired ?? At what point is my job over when do I get to clock out and call it quits for the day ? Im the one who got no sleep. I still got up with our toddler after pulling an all nighter I cooked breakfast took care of the kids all day did bath time cleaned up the house before bed cooked dinner cleaned that up put our toddler to bed etc etc etc but when I ask for help, HES too tired. I literally broke down crying this evening telling him how exhausted I am and how long it’s been since I slept and he said that since he’s off work tomorrow he was gonna take a turn and stay up with the kids tonight and let me go to bed since I haven’t slept. He promised me he would stay up with them and said he’d even drink an energy drink tonight if he had to. I go to the kitchen to wash bottles which takes like 15 mins or so, I go to the bedroom and he’s in bed dead asleep. So here I sit at 2:35am STILL awake with our baby who is again refusing to go to sleep. I am seeing double from the lack of sleep. I’m so beyond exhausted and so angry at him. I’ve tried waking him up and he just rolls over and faces the other way. I’m genuinely wondering at this point what would even be different if he wasn’t here? I do everything inside the home anymore as far as cooking cleaning taking care of the kids you name it. The only thing he does is work outside of the home and he thinks that’s an excuse to do nothing at home. I’m genuinely considering leaving him over this because I just can’t do it anymore. I’d rather do it by myself and struggle alone than sit here while he WATCHES me struggle doing it alone. It’s creating so much resentment and I don’t think I’ll ever get over it at this point.
