... stuffs is always interesting, but to find something out via an unexpected source (ie. A tells me about B) can actually be quite upsetting. The seeds of doubt are now planted, as you no longer know where you stand, since you cannot comprehend why the people involved never told you themselves directly. Your mind starts to wander and wander and wander ... and somehow you end up being so tangled up that the only course of action you can think of is to avoid them and to expect nothing in return ...
It is a protective mechanism and maybe, just maybe, there is a hint of punishing someone here, since cutting someone out of your live is blatant and cruel ...
So I am not sure what to do ... but to accept what we cannot change/turn the clock back, is one of the hardest things on earth ...
