I also have an unpopular opinion. I think if you come out while you're still married, it's going to cause your wife, even if she doesn't think so now, a lot of embarrassment and pain. People who don't know the two of you well will gossip, and they'll find a million ways to imply, amongst each other and behind your backs (even openly to your wife) how this must be her fault for failing to satisfy you.

Has your wife known completely that you are 99% gay? If she had known you were 100% gay, would she have married you?

I just don't see how coming out will be good for her in the parts of her life that she has to deal with alone.

If you divorce and then come out, at least this allows her to save face as a woman with good self esteem.
