his tone isnt wrong
he is just stressed, overworked and feels underappreciated
i went through something similar when I was 17
I had already moved out, was working my ass off(driving exotic dancers @ night and working @ a machine shop to pay bills) as well as going to high school full time(i was a junior).
my 15 y/o girlfriend was abused by her father pretty grotesquely so I took her in. Knocked her up and we were scared but I was like "fuck it, i am a man I can deal with this"
anyhow the next year of my life was the most godawful mess you could imagine. she went into deep depression, tried killing herself, killing the baby, killing me. she would completely destroy the house, dropped out of school, did heavy drugs, fucked other guys...you name it
but i still kept plugging along because I felt it was the "right thing to do" to get this baby into the world. I didnt want CPS taking the kid away, or her, cause i thought I loved her. i felt i could shoulder all the burden myself. It almost destroyed me. I was so beat down, emotionally, physically and financially. scared to death the child was going to be fucked up, scared she was going to be fucked up. scared about jail for child abuse etc I didnt know what to do.
it goes on and on but anyhow the point is when a person feels unappreciated it generally means they ARE and something has to be done. relationships do need to be win/win
IMHO the original author needs to empower his wife to take a greater interest in furthering her professional life or domestic life. But he has every right to be upset and vocal about his needs and wants and set agreements between them to create alignment in their relationship
