As a person who took the risk and told, after years of guilt and lying and hiding and all that, all I can say is damn right!
I've witnessed (and been the recipient of) too may "tell tell tell" pile-ons on this forum. Telling is a double edged sword. It can be the best thing you ever did, or it can be the mistake that blows up your life for no good reason. To presume that some well meaning stranger on the internet can know enough about your life and circumstances to really tell you what the right thing to do is ... well ... it aint a good idea.
All any of us can do here is share from the perspective of our own experiences.
Speaking for myself ... there have for sure been ups and downs since telling. On balance the highs well outweigh the lows, and in a lot of ways it was the best thing I ever did. But on the other hand, it has complicated my life in ways that are pretty tough to deal with and sometimes it feels like a living hell ... still, living in the closet was also living in a different sort of hell.
By the time I told, I was darn sure that regardless of the outcome, this was the only decision I could live with. Nobody else can get to that point for you, and nobody else has to live with the results but you and your family.
If closet haters be hatin' pay them bitches no nevermind.
They don't gotta walk in your heels, girl! :-)
