I wanted to post to help people who might be in the same situation.
I was married and left my dh after 8 years together (we have dc together) I left him because I just didn't love him. I settled for him when I was young (probably scar d to be alone) and come to my senses and left. It was the hardest thing as he was also emotionally abusive. 4 years later I'm with my new partner and I love him more than life. Cringe i know (I'm insecure a lot probably due to not being able to believe I've finally found someone I love as much as they love me) but life couldn't be more perfect.
If you're wondering whether to stay for the kids please don't, I'm so glad they can see what a happy fulfilled relationship should look like.
