Good for you !! Sounds like things are great !!
Your group of friends will probably shift in time. Hopefully to a group where you don't have to hide things from them. Friends are people who support us and love us right where we are. If your friends can't accept what's going on with you, then maybe it's time to begin to find some who will. Chances are, a lot of them would be more supportive than you think. Too bad that you feel like you have to hide things from them.
