Problems with Middle Age Step Children

My husband has 3 grown children 52, 49 and the youngest is 45. I am younger than my husband but I am near 60 years old myself. The children and I only get along if I am their maid and say nothing.

My husband allows the middle son to come and bring his girlfriend to stay with us for 2 and 3 weeks at a time. Mind you, they never clean nor cook and they change my furniture around to suit them. If I say anything it's a big argument. The 45 old old son lives now about 3 and 1/2 hours away and is now married so they come 2 and 3 times a month and stay from Thursday until Sunday. They never clean or cook or make their beds. My home is always in a disarray until they leave. They must have breakfast every morning and a 3 course meal at lunch and dinner because my husband says they have to eat. If I disagree it is a big argument.

No, I don't work outside the home now. I worked for 26 years before I lost my job. I have worked for a total of 35 years and raised 2 male children of my own alone.

My husband is not a well man, but I take really good care of him. No one else but me. I am so tired. He thinks I need him to survive because I have no money. But I can leave and take care of myself as well as take care of his grown children.

I took my vows in the eye sight of God to heart, I do love my husband. I am supposed to be responsible for my husband and not his grown children. He is suppose to show me the same regard. I am at my ends wits. Any thoughts?
