Same relationship problem for 4 years

It’s been 4 years since we had our firstborn, 2 years since our second and I find myself STILL frustrated, arguing or airing out my thoughts over the same damn topic of my partner not helping out as much as he should at home and with our kids. I feel like me being frustrated, annoyed and upset over the same thing most days when it gets too much for me is wasting my time because he still can’t/won’t change, step up or acts like I’m overreacting or my feelings aren’t relevant. I finally realised I’m most likely better off walking away because it’s been so long already he won’t ever change 😪
