Search Results: giving a guy your number

To make a long story short:

-My good female friend has an alcohol problem
-I'm always there for her and do the best I can to support her, but she sometimes complains i can't help her good enough because im not an alcoholic too
-I thought it would be a good idea to give her number to one of my online gaming buddies who i know struggles with alcoholism too
-He starts to text her and acts weird... he starts asking her relationship status, she said she had a bf (but doesnt), then he says "oh well you should let all the guys know in your life that you have a bf" and she got mad and said "dude im looking for alcohol advice not social advice!"
-I text her the next day "Hey so i gave my friend your number to try and help you since he's an alcoholic too, hows everything?"
-she texted back "Haha I knew you were involved the moment he asked me about my relationship status. its as if you were trying to pry for information" she then started to cry on the phone and said she felt i backstabbed her. She also accussed me of trying to get him to troll her for fun

I don't get what I did wrong. she doesn't talk to me anymore and i lost my good friend. how do i get her back, and can you really say i did something wrong? I'll admit I shoulda asked her permission before giving her number, but thats the only wrong doing i can see i did. i have no control over the weird actions my friend did, and i told her that! she said back "Well you shouldn't have sent him if he was a weirdo! do you think im retarded because im an alcolholic and wouldn't find out you were involved?"

but its like... i was just trying to do something nice for her and help her. Help anyone?
