Venting

My boyfriend and I have been together for now almost three years and lived together for almost a year. Between the both of us we have three kids. But as of lately I feel like I'm raising a fourth child. I work two jobs (he has one) and then I still come home clean, cook, etc. while he just "games it up" with his friends online. I'm fed up I've tried speaking about it and it seems to change for awhile then things go back to the way it was. To top of off our sex life is like on a decline. I feel like I barely get any attention from him. It's like I'm the man and woman in the relationship. I want to work things out but somethings I think there's no point.
