She drinks because she's addicted. She may try to blame you, but it is in no way your fault. She's carrying a lot of shame and she's going to be defensive to protect her drinking. She thinks she needs it in order to cope with herself.
You didn't cause it, you can't control it, and you can't cure it.
We all judge everyone every day. She probably does resent it. Alcoholics run on anger and resentment. That's pretty much the default setting.
Just take care of yourself. You deserve better.
