Lil and LFL are giving you great insight on how important allowing and excepting the changes of each person in a relationship is. This is something my H has a large problem with he does not like change in myself and has no drive to change himself. How to make your wife see that the changes are good and are apart of yourself not just brought on by the other woman. I do not think you can make her see this until you do. You yourself have given other woman credit for these changes several time. While it was you who made the change she only helped facilitate it. Your wife has changed since taking on the role of motherhood. You yourself while trying to accept these changes have had a hard time adjusting to some of them. She will also learn to accept and adjust. You have had 4 years to do so she has had a few weeks you might just want to give her a little time.
