Letting go doesn't mean that person is no longer in your life--it means--you simply don't care what he/she thinks of you any longer. AND you have quit letting he/she take away from your happiness.That was my happiest moment!
ALWAYS be confident in your decisions. Live life for you. If someone doesn't like it i guess they don't have your best interest in mind. only you can make the decisions that will change your life into what you want it to be.
