It's worth asking yourself whether you /want/ to like your kids. Would your life be better if you liked them? If you don't want to like them, why not? If you do want to, how might you go about that?
I hope this doesn't come across the wrong way, but a therapist can be a really good platform for talking through and exploring things like this, which might be hard to discuss with friends/family/etc.
Something along the lines of “a man is complaining!? hahaha look everyone, a man feels a tiny bit of oppression!”
and never addressing the complaint
If somehow an internet stranger can change your perspective, I happen to find kids (actually, I view almost everyone as fundamentally) insanely intelligent and interesting. It's probably because I don't have kids that I am able to be in a less stressed position, but I find that watching kids grow is fascinating and frankly.. fucking incredible.
(for me) It's similar to learning about how insanely complex soil life is. Mind blown.
I know for a fact if I had not begun to come to terms with my own self and all of the things I don't like about myself over the past two years, I probably would be extremely critical of my kids as well. But I have learned to allow my critical-ness to manifest thoughts (as it always will) and then to let those thoughts go.
Lastly, all the talk about more fulfilling lives etc. How would you know anyway? It’s not like you took both paths and then compared.
