Resenting my husband

Hi there please I need help. I am resenting my husband and possibly thinking this marriage isn’t going to work after we been together for almost 9 years and almost 7 years married. When I met my husband he had 3 boys which I love very much. I was young at the time with my daughter who was only 1 which I had from a previous relationship also. We became a big family but from the beginning he always put way to much on me. He used to leave his 3 boys with me all the time. Say he will be back, leave and not come back for hours. I put up with it for a long time. By the way the mom is not a good mother and barely sees her kids. She also got to live her life and not help with her kids while we did it all. So I always been the one helping a lot. Now the kids are older and getting a lot easier to take care of. We bought a house together and we all live as a beautiful family together but not exactly perfect inside. I recently lost my job 3 months ago and that was due to me not doing the right thing by the job because I was so stressed out having to drop kids to school in the morning then rush to work, rush home get kids to practice. Mind you I was having to pick kids up at 2 different schools and get home and get them ready to go to softball practice then rush home at 7…. Shower them… feed them etc. Now I just got a new job working full time. My husband always comes home from work and sits in the car on his phone talking to his uncle laughing and says he’s handling bills for hours while I’m inside doing dishes, cooking, showering 3 of my little ones for bed time. He gets to just sit outside in the peace and quiet and not help me at all inside. He gets mad when I don’t want to do anything sexual with him because I’m tired. Am I wrong for not wanting to be with him because of him not helping me like he should ? I’ve told him so many times how I feel and he still won’t change or be understanding if anything it’s always a battle. Please someone give me advice on this. Thank you.
