Bees who have been the ones to initiate a separation/divorce, tell me how long it took for your partner to accept it.

I’m ready to walk away but DH is having an extremely difficult time accepting this. I’m trying to be empathetic and gentle with his feelings but it’s hard when I have experienced so much heart ache and disappointment over the years. Obviously I’ve had more time to consider this then he has since I’m the initiator, but I just want this to be over.
