That 'doing it for a while' part is one reason I don't really like the "only as well as you love yourself" truism. One can absolutely care deeply for others without caring much for themself, at least to start. But to your point, unless you can develop [/an awareness of the] strengths that you bring to a relationship, fears of being a burden, failing, or taking too much will put a steady drain on it.

I think the biggest thing that the "self-love prerequisite" idea misses and that the article sort of indirectly gets at is that this feeling of social self-efficacy is something most (all?) people learn through successful relationships with others - sometimes in our upbringing, sometimes not. I don't think it's unnatural at all for others' love of us to outpace our own just a little.
