I think it was you (yes, I'm taking a brief moment to post today, it's going to be rare though) who said you'd be interested to see how your H would respond if you were sporting a major rack.
Rethink this. The only reason to get breast augmentation is for YOU, not for other people's reactions or perceptions of you (if this was you who said it.) Doing it in hopes of something happening....will lead to disappointment.
One of my dearest friends had the following done, hoping it would affect how her H reacted to her.
#1 Implants (pretty good sized ones too) #2 Tummy Tuck #3 Lipo, arms, tummy, ass, thighs
This made absolutely no difference whatsoever with how her H reacted to her....nada!!!
I feel like I can say confidently too that if I looked like those bleached blond whatever you want to call them's that my H had been viewing.....he STILL wouldn't react differently to me. Why? Because it's not the physical me he has an issue with....it's his own demons inside him and the relationship between us.
