You’re not weak—you made the best decision that you could at that particular time. There is no point in trying to discuss something when a person is intoxicated; they will just argue with you and probably won’t remember. You’ll know if you feel like talking with him in the morning or not. I know it’s hard to just put up with it. For a long time I lived with keeping the status quo because I had to so that I could keep everyone safe and the A unaware of my plans to leave. Best to you.
