Awww Trippin!! *hugs* ... I know that feeling!! Sometimes I keep some of my "secrets" to myself but feel awful when something happens and my hubby is clueless.
I think it took guts and love to say that to your bf and I think in the long run, he will love you and appreciate you for it!!
I am sure everything is ok now and maybe now you have an added support for your secret fear that you didn't even count on having!!
