Sweetie I know your disapointed..... I would be too, but in talking with many As at meetings and such.... alot of them slip, maybe this is a slip.... We can hope. Im very sure he is feeling shame and guilt and 1000 other emotions and that is the reason he cant talk to you... his just trying and then cutting you out tells you he wants to but probably cant.
Dont jump to conclusions yet hon... ride it out, focus on you and if you can catch a meeting that would help you soooooo much, if not see if you can pick up some books and do some reading. Disconnect and focus on you... you got your answers and now you dont have to keep checking... Let him work his recovery and you work yours.... you will know soon enough if it was a slip or if he just is not ready and then you can look at your options and make choices.
Im glad your taking the boys and doing something... It will help to step outside of it and focus on something else.
