Is it dangerous to live a double life (kinda)?

Anything you put online can come back on you later. Sooner or later someone will make the connection to one of your relatives you will be outted. You're better off just coming clean with the people close to you. If they can't except it, the problem is with them and not you. Perhaps there may be initial upset, but after a while they'll remember your son and will love you. If they don't, then you are better off without them. Otherwise they'll leave you locked into a life of misery.
