Lestersquare - Glad you found us, & welcome. Good things have been said already, so I'll just say - it's early days yet for this whole process, so try not to be frustrated.
I've been on both sides of this thing - so I can understand how resentful you are. When I went into rehab (only stayed a week due to insurance issues) I wasn't permitted to talk to anyone about what was going on. I was allowed one brief phone call a day, and from a pay phone - so there were people standing in line waiting to use it & I wasn't really free to talk. I'm sure I sounded strange to my family. When she gets home it may be entirely different.
I do think al anon would be a great idea for you. I'm sorry for all you've been put through because of this horrible disease. Let us know how you're doing.
