The OP says trans, but not trans-what. I have stated I am transgender for at least a dozen years. I am now working through my transsexual feelings. So to me, it isn't a transition as much as a realization or step in self awareness.
For Vanessa, I don't know that I pushed it aside. Either I did subconsciously or my feelings just deepened over the years. Addressing the family is probably different for everyone. I have long let some family know and there are some others I would tell even without transition. Others I was holding back on as they would be more difficult to educate. They may just be getting it anyway at this point. My wife is highly supportive to the point of saying "just do it, the back and forth is more stressful". She says she loves me no matter how I look. I suspect she is sticking around.
