NB,
i can so related to how you've handled things.
i had a feeling the bomb was coming and when it did, i was almost numb. he was an emotional wreck but i was numb and ready to get it over with.

for some reason, i think my db face and not showing any emotion when he goes on a temper tantrum has made things worse.

on the nights when i made plans and came home late, my h would be hostile the next morning and start pushing for separation and divorce.

now that we've separated and i didn't need him to help me with anything, i don't know if i'm sending him the message that i don't need him so maybe we are better off apart.

i still love my h .. i don't know how or why but i do. maybe it's the compassion that i'm feeling.
but i also don't want to sit around and wait for him to file. i am seriously contemplating filing myself and serving him with what he wanted.
