There’s no clearer degree of self-interest, imo, than the simple fact that single and childless women live longer lives, while married men live longer lives.

Everything else regarding relationships, in my opinion, is downstream of this.

Perhaps this may change over time, but it seems to hold fairly robustly across place and time.

Thoughts?
