Patience, patience, patience...if nothing else use Job as a role model...I know my wife had a really hard time understanding, first she thought there was the other woman, then she thought I would end up a woman, but alsa I only dress...after some really long talks, lots of tears and a great deal of understanding from her we came to an understanding...
She has been a supporter since then, not only for me but also for the equal rights of everyone...no matter who. She is my makeup artis, photographer, but most of all she is my wife and my lover...
Above all there must be total truth and honesty between the two of you...
Hope this helps, Good Luck...
