This past few nights i noticed that my wife feels so tired . Every time I ask her if she's okay she always answers me that she's fine .Im worried about her, what would I do to help her get into it?

Mark I think your wife need to be check by a physician perhaps, she might so tired doing a lot of things at home thats why she is not feeling well. Let her rest and remind her not to do tasks for now , understand her well and help her by showing of course your love and care to her .
