Jodie,
It's no longer about his addiction, his ex wife, his kids or the new girlfriend.
It's all about YOU, about why you allowed him to treat you the way he did.
Why you kept going back for more.
Why you felt you didn't deserve better.
I think you are going to discover that all your ager is going to end up going inwards and I hope you continue therapy to help you discover all your own whys.
