<human>: Can you give me the gist of the text in a nutshell?

Been together 10 years, married 7, have had three children. We are generally happy and don't argue very often and even when we do, its more fun that it is annoying.  She has been on antidepressants for a few years now and they keep her in a general good mood, but aside from taking care of the children it seems like she is a robot. She doesn't have any interests or desires. She is willing to have sex whenever i want but only if she doesn't have to move.

I know her main frustration is with the fact that she is a stay at home mom and we can barely afford to live on what i currently make. This fills her with guilt when we cannot afford something for the children or have a car/home issue that needs to be paid for.  

I try to show her affection to let her know she is loved and appreciated for what she does, but i don't know how to change things. Any advice redditors can provide would be appreciated. Thank you.
<bot>: Want to make wife the girl she was when i met her, but financial stress and kids seem to have sucked the life out of her...
