Mother's husband won't comply...?

Why is it that when the husband get's ill...the wife does'nt complain while she's taking care of him and his needs and doing all possible things so that he returns to good health and well being...and then when the wife has an unexpected mis-hap that causes her to go to the hospital and unfortuanately have to have surgery, then when she's released to go home...she has to have after care(home bound),her husband seems to be resentful of having to take care of her? he's always complaining about administering her med's or having to massage her legs and feet because of her swelling. He feels that her daughter should be coming by and doing the things that he should be doing as a husband should do. On top of that...this man is a Pastor, what is the real problem here? does it still stand within the marriage vows that you are joined together for better or worse? and in sickness and health? a good wholesome honest reply will do.
