100% agreed.
Mating is not like throwing a dice: we DO choose our partners.
One or two times it might be bad luck, yes, but a series is definitely evidence there's something underneath.
And although most people will say "But I didn't know him/her in advance!", time and again it's clear their unconscious mind has chosen someone that "clicks" with their own traumas or issues. This comes up all the time in therapy or couple counseling.
Think about it: the ONE common thing among all your exes is YOU.
