That’s the real communication chasm, because for me - not talking is way way harder. When my S.O. isn’t open with me I assume they’re making a deliberate choice to withhold information to hurt me or appear strong. Either way they’re excluding me from their life, which means they’re ready to move on and don’t love me anymore.
A state of being in which you find it harder to talk than not to talk is so alien to me it’s beyond imagination anyone could exist in such a manner.
