Tatts, this sounds more or less what happened to me, my thoughts are that you should walk away and stay away. All the ties that you must have had have most likely been severed or changed beyond recognition.
If you can, walk away, start again, i had to realise there was something that sent me away and i had to think whether it would ever change. I didn't go back.
The hurt gets easier, now i have anger and determination to get on with my life. But i am happy.
These are only my thoughts, best of luck.
