We are all here Mo don't worry. It may feel like middle of a war zone but you are kicking those punches and waving that sword like a pro. Look how far you have come- at one point even the thought of ringing women's aid was to over whelming. But you have:
Rung them several times
Told family and friends the truth
Got legal advice not so good and good!
Rung a refuge
Started a benefit claim
Told him it's OVER X 57
Had the this is maintence like it or I go after you for it chat.
6 weeks ago that seemed to many mountains to count and yet here you are right in the middle. Yes ok so you have to tell the kids and face him and sort other things but the biggest emotional tasks you have done all by yourself.
I know it's draining and not over yet but you are fighting for the best reasons for you and the kids it's all good stuff to come even if it's a new start away. I doubt you will have a major wobble you are not going say ok come back let's try again are you????!! You have legal /house/maintence law on your side it's ok to let other people take over and fight these things for you. You will get there xx
