Dear Christian GG -- I take it by your signature name that you are a Christian woman, yet your statement about fame (and I suspect the monetary gains from that fame) would indicate to me that your thoughts are more about that fame and money (remember that the lust of money is the root of all evil) than about your husband.
Your three-day retreat, I guess, was church-oriented and it was there that you were urged on to "treat the evil" that your husband was doing. In one of the books of the law, it states that a man shall not wear a woman's clothes. Right? Yet it states the converse, too. Do you or any of the other women of the church wear pants? And don't give me that line about them being women's pants! Besides, that scripture is interpreted as forbidding a man from sneaking into a woman's quarters by guise or from joining the pagans in rites using crossdressing as part of sexual orgies, or from a man dressing in a woman's clothes to avoid military service or a woman from taking part in battle. And how about the other laws around that scripture? Do we wear tassles at the ends of our clothes? Or build parapets around the roofs of our houses? Mix different materials in our cloths?
Please, back off. Give your husband some air. Sit down and talk with him without hostility or self-righteousness. Listen to what he says. And remember, none of us asked to be this way. Many of us have tried to stop. Some of us have even used prayers (and a few promises to God, if ..).
Sorry, I rambled on. And please, take my post in the manner I meant it, with my love in Christ that you two will work this out.
