soul mates are good only if they do us good.
If they are bad for us, then we can pass with soul mates and have another loving person near.

She made other choices. Choices not to heal, not to step out of her problems but to add problems to existing problems.
That's her choice and you can do nothing about it, i guess.

The only thing you can ask yourself is whether you agree with those choices and if they are any good for you.

I don't think she feels like your soul mate when she is under the effect of crack, or is she?

Is there any group, even online group, to talk about relationship dependence, because you seem dependent, maybe not from the girl herself, but from the idea of the perfect love you had.

When you say that she is your soul male, you are talking about how your girl was or how she is now?
Because people change, you know. Sometimes for the better, but not always.
