In a relationship but feel like a single mom

I feel all the stress , all the pressure, all the worry , he has no cares although we are in such a shitty situation. I just feel like since im the only one concerned about my familys future and well being. I might as well just be single doing it. Because being in a relationship and getting no help or support makes me angry and feel so alone. Been waiting for a change for 2 years.
