Небо
Auto-translated
Well, if we take your idea a bit further, we can conclude that being a "breadwinner," especially in our time, is essentially the same as being a cuckold, as you described it. You sacrifice disproportionate emotional, financial, and time resources just to put a big checkmark on your life and get nothing in return. And your own child won't even thank you for bringing them into the same world where you suffered. Whether you have a partner or not is a secondary issue.
