agreed, don't go back... he is in big trouble it seems... I think if this were me I would tell him so and offer my deepest concern for his well being and safety. I think I would tell him that I don't feel safe and that is why I am leaving. I think the last thing I would do is ask him to find me in a year, and I would find him so as to check in and see how each other is doing... then I would go and find new friends (the ones you have between you you will have to chose very well... no one that close to them or you), new prospects and a new take on love and life before finding other partners and love in life.
Anyone want to be friends on Facebook?
