my cancer is destroying my relationship with my hubby

Hi all not been having a good time of it of late, 4th dose of chemo 2morrow and i'm not looking forward to it. I'm about to have a good old moan so if your not on a good day switch off now lol. I really don't no where to start, I was diag with advancened stage 3 foli last Aug and started chemo in march, I have 3 of my own children, 2 of which live with my husband and me and 2 step children who also live with us. I have found chemo fairly tuff with aches and pains, chest infections and sooooooo tired, numb fingers etc but to top it all off my marraige seems to be crumbling around me. I have to try and carry on as normal with cooking cleaning , looking after kids etc while my hubby just sits on his xbox for hours on end knowing im struggling, i really would be better off on my own with just my kids to look after. Last week i just flipped and was prepared to walk but can't face all the heav ho of it all at the min and he has made it clear that he is not leaving. (thanks). I thought this would bring us closer 2gether, we are not 2 bad off with money as the morage got paid off as we had crital illness. I no a big part on his side is we are not having sex but i really don't feel like it and sometimes i just really want my aching legs a nice rub but he can't even seem to be able to do that. Anyway after one of our many arguments of late i have got to the bottom of the xbox obbsession, while he is on that he can 4get about my illness, he says and he has no energy to do anything else, all good and well for him but there are times many times when i feel totaly crap and really do have no energy and have to do EVERYTHING while he is forgetting about the illness and me. This week bless him he has tried but has told me he don't think he can keep it up,(must be missing his game). He never seems to talk to the kids either and this is a real bug bear for me but he has even been talking to my little girl, now thats not hard is it. My other boy bless him just wants out of this marr, and he also has his own problems as he has dyspraxia so can be very hard work at times. Has anyone else found that their relastionship is suffering due to cancer and its treatment
