I agree with Supercrew. I think by her manipulating you she was hiding her own deficiencies. She probably didn't realize her thought process in asking you to drink. We think differently -especially while recovering. She didn't know how hard it would affect you.
But now you know one of your weakness' and you will need to work on that to be successful and not drink over a situation like this again. There is alot of temptation during recovery -that is the point to overcome them.
Hopefully, you find a better support system. Wishing you peace and strength.
