I'm starting my life all over again after a certain age, so I find your words so inspiring! Please do NOT allow people to take your happiness away. Remeber that you are "sexual, powerful, opinionated, full of laughter and learning." There is absolutely no need for a "Be kind to 50 year old women day." You are not a victim, you are a strong remarkable and full of youth but mature woman. If people say otherwise, who cares?? let them say, you know the truth within yourself.
When it comes to new relationships after a divorce, don't settle for the ones that you have to change the way you are, there's a lot of fish in the sea. If you feel happy, great, if not, it is okay to let go.

Best,
CF
