I'm resentful towards my wife for being sick with several illnesses for 2 years
Why would that make you resent her?
I'm resentful because she was a stay at home mom and not a working mom.
It's wrong to resent someone just because they have illnesses. You should be more compassionate towards your sick wife.
Dude I'm tired of always helping her with everything. I'm going to divorce her ass.
How would you feel if you were in her situation? I don't think you'd want to work either. Try to show a little more empathy for your wife.
