Hi, not sure if people are still following this thread, but thought I would update 
Please excuse typos, I'm on my phone.
I moved into my new house a couple of weeks ago! Me and my DC are very, very happy.
On moving day my friends and family rallied together for me and fetched furniture, put it all together for me and filled my cupboards with food
I walked around feeling like I was going to throw up. The day after I moved in I had a MASSIVE panic, thinking oh my god what have I done. I think I was quite hard nosed about everything so it was only afterwards that it really sunk in, what I had done.
My Mum talked me through it, and within a couple of days when I had had time to process what happened I felt great!
My ex has reverted back to type, which proves I made the right decision. He has tried everything to make me go back but I think has finally given up.
He cannot BELIEVE that I haven't turned up on his doorstep begging to go back, he is genuinely shocked.
I told the kids and they are fine.DD loves going to see Daddy at the weekends for a sleepover, DS is too young to understand really.
I am truly, honestly, the happiest I have ever been
I don't have much money, but I don't care. I have no one to answer to, no one to criticise me at all.
The relationship I've got with my kids has drastically improved as I am so much more relaxed, not constantly stressing about the latest argument.
Only now that I'm out if that relationship can I see how truly unhappy I was, so depressed and snappy with the kids.
I want to thank every single person who replied to my thread for supporting me.
I have trouble explaining to people why I left him, as it was all such low-level bullshit over years and years. I recently read a post on the relationship board (I'm sorry I don't remember the posters name) they said that
Everybody has the right to not be in a relationship if they choose not to be
I'm not going to try and explain myself to people anymore, I don't need to justify it to anyone. I don't miss him at all.
