Not a Aibu, but I'm posting my update here as this is where I originally posted.
My previous thread about my arsehole of a STBXH, was full of incredibly supportive replies and gave me the massive push I needed to LTB.
I have moved in with my parents for the foreseeable future, my older dc have settled into their new school far quicker than I expected and I have a job! I start a week tomorrow. Who would have thought it?!
No more abuse, being called names, crying myself to sleep every night. I feel like a new woman!
