I've only told my wife, and it worked out fantastic, she is completely supportive and we are still very much in love. One thing to consider is are you okay with coming out? I'm still very much in my own shell, and it is very hard to get out of the mentality I have built for myself that makes me feel comfortable.
So I feel good that she knows about it, but I feel incredibly vulnerable and afraid. She has told a coworker, and knowing how things work, I am sure most of her coworkers know now, and that feels good yet at the same time I have not developed a mentality of how to deal with this.
There is a part of me, that wants this to get out to all of my family, to be thrown out and exposed for who I really am, it would be nice to just break myself into a thousand little pieces and rebuild myself - and that may be necessary. Another part worries, to death, I worry about my aging parents, the shame and guilt they would feel, my homophobic brother would be most impacted, he has always used me as an anchor for stability in his otherwise chaotic life. My oldest brother, who had his wife leave him for another woman, what sort of impact would this have on him? Would he see me as nothing more than selfish? He just had a kid, is he going to see me as a monster? Am I going to be perceived as a threat?
I know the spot you're in, it sucks. I would suggest a therapist first, if you can afford one, I wish I had one to sort through all of my feelings and help "me" build myself back up.
