You clearly have expectations of support of a certain kind from your boyfriend. What would have liked his response to have been at the 46 day mark?
And was it his lack of support that really derailed your sobriety? Or was it your resentment over unmet expectations?
He can't be a mind reader on this. You say you have communicated your desire for more support. If you have clearly defined what you mean by support, meaning, "I want you to _____________," then I really don't know what to offer, except This is who he is. Accept him as unconditionally as he's apparently accepting you.
