Hey, wondering if anyone could help with some guidance. My 40 year old wife starts treatment for stage 1 breast cancer tomorrow, and I need help in supporting her.

It seems like no matter what I do or say, it's the wrong thing and I only seem to inflame the situation every time. Things have degenerated to the stage where she says I make it clear that she's a burden to me, and that I feel I would be better off without her. She has further said she feels I hate our son as well, which is difficult to hear. 

I love them both so much, and nothing could be further from the truth. I try to tell my wife that but she claims I'm lying and I'm only with her out of a sense of duty and will shortly leave her when treatment begins. I can't claim to understand what she is facing but I can understand she's afraid and vulnerable and needing much better support from me.

Can anyone help with ideas of how I can get through to her that I'm with her no matter what? I can keep repeating how I feel until I'm blue in the face but she denies it, and worse then feels that I'm trying to control her. Should I just let her vent at me or should I try to find some way to make her see how I feel? The last thing I want to do is to make things worse and leave her feeling even more alone.

Thanks.
