Do you know anyone who has been "in the closet" for so long that they are unable to "come out" to even themselves?

I have an immediate family member that exhibits many, many signs of being a gay man (I won’t go into them, but, just to clarify, these are not stereotypical, shallow signs. They are behaviors, comments and situations that have occurred over the last thirty years.) But, he is so religiously conservative that being gay would completely destroy everything he has been about for his entire adult life. It saddens me to see someone so internally conflicted and unhappy.

Do you know anyone in a similar circumstance? Have you ever broached the issue with them?
