"Broken homes" are in many ways much easier for coming out. The parents aren't mired in marital and familial traditions, and in many cases they lack the moral stature to say anything at all about it.
I told both my parents, separately of course, when I was sixteen, shortly after coming out to my Grandmother (who is more a parent to me than those losers) and discovering that the world wouldn't come to an end.
My father said "Well, yeah, OK. I guess I already knew, but thank you for telling me. But not even tits? Tits don't do anything for you? Wow."
Mother said, "I still love you, but I can't approve of your lifestyle," to which I replied, after rolling in giggles on the floor, that her approval wasn't required. I didn't say aloud "the approval of a thrice-married abusive drug-addict who was at that time shacking up with a biker so skungey the Hell's Angels wouldn't have him...well, it just doesn't mean very much."
Grandmother was and remains the hard sell. She sent me to a family counselor when I was fifteen, recommended by her pastor, to "fix" me when she found a Chippendale's calendar under my bed. The counselor was a very kind man and referred me to the psychotherapist down the hall; I think he must have told Grandmother I was borderline crazy and needed more than he could give me. The therapist spent much of our sessions convincing me to come out to Grandmother.
So my sister was still living with us, then, and she was in family counseling, too... a different counselor recommended by her school advisor. During a group session, in which Grandmother complained ceaselessly about my sister, the counselor tried to deflect things by asking her "well, what complaints do you have about Bobby?"
Grandmother was caught off guard, and she was in full-on kvetch mode, so it came tumbling out: "I think he thinks he's gay."
"I know I'm gay," I spit out after a moment's struggle, using up all the courage that eighteen months of psychotherapy had given me.
She hmphed and crossed her arms and stopped participating. I don't remember the rest of the session, but Grandmother never mentioned it again. She stopped paying for our counselors and therapists, though.
And she still doesn't mention it, refuses even to acknowledge it when it comes up... and it does come up, you can't live with someone and never mention being gay. She doesn't like it, but she loves me anyway. And she supports me, too... not just financially, but emotionally. She got me to go back to college, she helped me quit drinking, she's just been there for me all the time...even times when a man broke my heart.
"The gay thing" is the only real fly in our domestic ointment, and sometimes we have bitter fights about it, but if I don't dwell on it and she doesn't dwell on it we're OK... and considering all the other things we differ on (I mean, she's a Christian and a Republican and thinks Bill O'Reilly is the Messiah), that's not so bad.
And something that got me through all of that was knowing that it wasn't my sexuality that was a barrier between me and her: it was her religion that made the barrier. She wanted to accept my being gay, but her religion and politics stopped her.
