Hi Partner,
Your wife is grieving - this is pretty normal for women with breast cancer when they realize the statistics on breast cancer, and have to come face to face with the fact that this thing could kill them. I know - I've been there, and as a nurse took care of many other women who've been there, too.
So it's good that you support your wife, and understand that she needs time to grieve. But don't let her grieve too long - she really needs to embrace the fact that she isn't dead yet, that she doesn't have an expiration date stamped anywhere on her body, and that MANY women successfully beat this thing through acts of will, sheer determination, and taking on a lifestyle that creates an inner body terrain NOT conducive to growth of cancer.
The temptation for many husbands would be to say,"come on, I need you, the children need you." I recommend rather than saying that, that you and the children gently invite her back into the fabric of your lives. Ask to sit down with her and keep her company while you read a book, or have the girls go to her and ask to sit down with her while they do their homework. Gentle reminders like this from her family will help her recognize that she has much to contribute, and that partaking in the life of her family is much more fulfilling than hiding herself away.
Also, let her know that you find her attractive, that you want to hold her in your embrace, and that you are all in this together. Make her feel wanted and loved, in a very gentle way. Reaffirmation of her place in your heart will help her to regain confidence that she can help meet the needs of the family. Let her know that when she's tired, you and the kids are there to help. Fix her some snacks - favorite foods that she likes, and sit and share them with her. Concentrate on simple non-demanding things that will help her focus on the here and now, rather than what could be.
I hope this helps. Please make sure to take good care of yourself, also.
Sincerely,
Tre
