Are you sure he has cancer? That was my first thought. My second thought was that if his behaviour has already been a problem, why would you feel you have to stay with him? I am sorry if he does have cancer - as I would be for anyone with it - but that doesn't change the fact that there were already many challenges in the relationship. Others may disagree, but I think you would be taking on more than you can - or should - cope with. From what you have written, it seems you are constantly justifying why you stay with him - making excuses for his behaviour eg. it's because he is out of work etc. It's kind of like marrying someone who has already shown that he is abusive. Why would you do that?
