I feel like I'm having babies with an inconsiderate asshole

The guy I've been with for 3 years is a rollercoaster himself. Never know if hes ok or in a bad mood. Long story short, I still live home with my parents. They take good care of me and are making sure my babies and I are perfectly taken care of while I'm out of work. My dad does more than a lot for me. My mom is the same way. Im used to doing things on my own so it was a kinda tough transition. Fast forward. I recently had a baby shower and my kids dad was a 1.5 hrs late.. his excuse was I didnt tell him what time it started. He didnt help set up or clean up... or take any gifts home. I spend the night with him on the weekends since he works during the week. I will get to his house and wait on him because I gave the house key back when we broke up once and never asked for another 1 for my own reasons.... but anyway he will pull in and go right in the house.. knowing I have things to bring in. He never helps me carry any bags, nothing heavy whatsoever. Im not sure if im spoiled or I should be carrying things on my own. He thinks he can help hold my legs up when it's time for sex but cant help hold and carry bags. He is so inconsiderate and its up and down with him. I got pregnant when I was winging myself away from him. I hate I got myself into this with him cuz hes actually showing me i will be doing most of the hard part by myself... well without him. Im fine with that but he does financially help me since im not able to work. Thats not something he is actually 100 percent willing to do either. He acts like he doesnt want to help me so anything. I have saw the signs long enough but I honestly thought he would change. I just dont even want to be with him anymore.
