going through something similar
I hear your anger and pain for your wife. My hubs recently had a split-up and the anger I felt was a real surprise to me.
How dare this person not be as appreciative of my wonderful Hubby!
I think this is a side of compersion that doesn't get talked about much...or maybe I just haven't stumbled across many stories about it yet.
Thank you for sharing your feelings. It is affirming to know that I'm not the only one who has felt this.
The good news is that she still has a strong relationship with you and the assurances she needs that she is an amazing person. Points awarded for your love and consideration of your wife.
