You know one of the worst things about this is, she is my best friend. I find my self in a paradox. I have a problem with this MLC, and in my mind I wish I had her to talk to about it. I miss her company, I miss her being there when I get home.
I completely relate to this too, I don’t know if this will help, but maybe start having an internal dialogue with the “old” version of her. Tell her how you feel, how hard this is etc. and also keep noticing how this old version and current version are different. This was very helpful to me early on to both feel heard and to detach as I really could clearly see the reality of how my wife is not my friend as she is now. It’s all part of grieving and acceptance.
