This thread resonates with me so much. My abusive ex left almost four years ago now, for another woman.
While I was briefly devastated, I soon came to realise that I would not miss:
How political leg shaving and hair straightening became "who are you trying to impress"
Him going out "for one" and rolling back in at 11am high on drugs
Forced/coerced sex
His lovely, shower dodging ways
Being called useless, desperate, pathetic and dirty all the time
How every nice occasion for me was marred by one of his drunken mantrums about something. Christmas, my birthday, the work Christmas party I had really been looking forward to...
Being woken up and scared half out of my life by an angry drunk man who wanted to continue an argument he had started hours before
Actually, the drinking in itself was a real problem. He was lovely sober. Actually, really lovely. He still drank and drank, knowing that it made him nasty and didn't care.
Being broken up with on Christmas Eve over a stupid comment and then receiving texts telling me I am a terrible person, come from bad genes, am the worst girlfriend that ever existed etc etc
So many. I'm really lucky to be in a relationship now where none of the above is a worry.
What I realised I liked was:
Hanging my stuff anywhere I liked
Coming home any time I liked
Having male friends
Making new friends
Taking opportunities I would never have even been allowed to consider before
Feeling safe all the time
Eating and drinking whatever I want
I'm still getting over it though, it takes time!
