Good for you GH. Instead of holding back your feelings and stewing about them all day you came out and were direct. Excellent!! I also like the fact that you changed the convo around by complimenting her. Fantastic!! I think THIS is key. I think we were lacking in the compliment and admiration department, we took our S's for granted and they started to feel tired and used. I'm sure OP complimented them alot and stroked their ego's like crazy (of course this was for their own selfish reasons but our S's were blind to that fact).
Your wife doesn't seem to like having deep emotional talks (I could be wrong) so the ring represents what she is feeling without saying it. My H has been wearing his ring for the last month. Of course I still wonder if he leaves it in the ashtray of his car all day and puts it back on when he pulls in the driveway (saw that in a movie once) but that is because of my own insecurities.
You seem to be doing really well. You have really transformed overnight. Go back and read your posts and you can see that you no longer come across as desparate and needy, you are now strong and confident!!
