The first year is such a milestone and something to be proud of..enjoy!
I see that you have worked through some things the past couple of months, I also know how hard it is cleaning up the messes we had made before coming to the program. Keep up the good work and number two will be here sooner than you think...
Honesty is the best policy-especially IF they are going to find out anyway, better to tell them your take than to have them wondering what you are about and who you really are. remember the ninth step ...when to do so would injure them or others...you are an "other" so feel out the situation and you should do fine
God Bless and Treat youself to something special...
