chronically ill and in pain spouse

My Husband is always in pain and I can’t cope. It’s been 4 years and his pain has been non stop. It’s fustrating. And he’s unable to chip in much into raising our child - and even when he does he acts like it’s the biggest most painful thing in the world. We both still work, so at least financially he’s not a burden. But he’s always in pain and we don’t go out much or have much of a life as he’s usually too sick or too tired to do anything. I know society doesn’t allow women to vent or be miserable with a sick spouse but I feel like this is not the marriage or life I envisioned for myself. I am still in my twenties and we have a small baby. I don’t plan to leave him. And I do love him. But I cannot imagine the next few decades stuck like this. It just feels so good just to write this. I would never tell friends or family what how I feel, lest I be seen as an uncaring monster.
