Relationship over.

I've been with my partner for 11years and I'm incredibly unhappy.
We've had a up and down Relationship, good and bad times. We've supported each other through a custody battle, deaths, toxic family, work issues, mental health and having 2 miscarriages but I'm just so emotionally and physically exhausted, I feel nothing for this man. We've talked through our issues many times, taken breaks, tried different ways of approaching one another with issues, we've talked to friends, counsellors etc but he's narcissistic and I'm always to blame. He's mentally/emotionally abusive and I just can't keep doing this with him.

We've broken up before but I always get guilted into going back (he uses money, house/cars etc and the kids against me). I now have a stable job and know I could do things on my own without him. A few weeks ago the kids and I went away and I realised just how unhappy I was and how I didn't want to be with him. I told him and he was shocked, cried crocodile tears and acted like he'd change which is his usual pattern. It's been 3 weeks since and he's shown no intent to change/or made effort to change my mind which I knew he wouldn't. I've applied for houses and been in contact with centrelink & child support. We are still living together however we don't share a bed, we barely see one another (due to work schedules) and if we are home at the same time I'm usually busy with the kids.
I feel like he's thinking everything is fine/normal and we will be okay but I don't feel that way, I've told him a few times we are done and I'm not doing this but within days he's calling me babe or trying to kiss/hug me.

Besides moving (which is bloody hard atm) how can I get this man to understand we are done?!
