Hi Rae - I hadn't read your older posts so am coming at this from a "fresh" perspective. I agree with what many have said here.
It is hard. I feel your pain - it is like a knife in the back when you hear your loved one "is happier than they have ever been". Maybe it is the "pink cloud" part of recovery? Maybe it is real? Maybe it isn't? One will never know.
I do agree that you need to focus on you. I, too, hung on to the drama of my ex, even after he was in recovery and doing well. I still struggle with it every day. I often find I "yearn" to have the drama back...how crazy is that?
Keep focusing on you. I also agree that some parts of his text were blaming/manipulative and still rang of someone who is new in recovery.
Focus on you and know that you have the support around you.
