Women reserve the right of deception, and judgement of what's unacceptable, for themselves. My ex considered my crossdressing as unacceptable, as according to her, it was a 'lie by omission'. Of course her own past history of psych problems, wasn't something she felt was necessary to tell me about.
Crossdressing, or altering the gender image that she was attracted to, is unfortunately something that can destroy any sexual attraction that a woman feels for us. Many women can accept adultery, even murder as acceptable in a mate, as long as he's still 'a real, masculine man', because she still has that underlying animal sexual attraction to him. But change the masculinity by being a crossdresser? Oh, no, that changes everything. And once the sexual attraction is gone, the romantic love can easily follow. Then, she will seek another male to support her feeling of being a desireable female, and that male won't be you. Once the romantic love is gone, often, so is the marriage/relationship.
It all depends on tolerance. If you never drink, a few shots can easily get you quite intoxicated.
