Well, I feel just the opposite π Their relationship seems to me stronger and stronger, and I still see deep love in their eyes, even if they try new things which they have talked and agreed about before . You mentioned "normality". Everybody has their own definition of normality. π For me "normal", here, will be what they have fun with but doesn't hurt anybody physically or emotionally nor, mainly, jeopardizes their couple and their love.
Thanks for the compliment in your previous post. Like everybody else I've had my share of happy and unhappy moments but I prefer and work on remembering and sharing the happy ones, putting the others aside. That keeps me smiling π
