Sometimes I feel like I should just stop helping my wife more.
Why don't you help your wife?
I'm spending more time on the computer than taking care of her.
It can be tiring to work instead of playing on the computer but you have to do what you have to do. It will lead to fights if you don't help your wife and take care of her.
I know, but she has to work hard as well.
You're right, you both need to do your part. However you spending more time on the computer doesn't help anyone. You should tell her to do her part, and then do everything that you can to help her back.
