need advice please

I have two kids a 2 y/o and a 10 month old. My kids father and i are not married and we live in his parents house. I am at a point where i am always stressed out. I feel like the only REAL parent. I do everything always and can not even shower or use the restroom alone.My boyfriend is always playing video games and either making me watch the kids alone or have his parents do it if i have to cleanup. I work 6 days a week. he works 5. my typical day wake up at 8am feed the kids change diapers and play until his parent come up . I then get ready for work and leave the house by 1030 i get to work at 11 work until 530-6pm. come home feed the kids dinner eat a little something and play, give them a bath if i didnt bathe them in the morning with me. Then i put them to bed at around 830-9 oclock if im lucky they will go to sleep. During this whole time the only help i recieve is if his parents are home or if i nagg enough. When kids go to sleep i sleep too. the wake up do it all over again and then when weekend come i work nights for 3-4 hours. The. come home at 9 and feed them put them to bed ..I really never feel happy unless its just me n my kids. I pretend to be happy i know it. I am always stressed out and frustrated and just feel like i deserve more. Dont get me wrong i do love the father of my kids. But i just dont know what to do anymore i want to be with an adult not a child. I want to be with someone who helps and takes care of his kids because he wants to not because someone keeps nagging at him to help. My family thinks i should just leave him and that i would b much better on my own. His family thinks that its better for the kids if i just stay with him and ignore what he does. But is it really better for them? Im reaching my limit. I just dont know what to do anymore. Any advice?
