Since I've been DBing, my changes have changed her in so many ways. It has given me a glimpse of just how good our relationship could be.
AND BY ALL MEANS, keep these changes and build upon them. I mean DO NOT stop. Keep bettering you, make the changes last. If you don't she will see this and it will make it easy for her to choose the OM.
BE THE BETTER OPTION. Make her feel like YOU are the MAN, not him.
