I was married to a ML/WL - I wouldn't say she lacked morals initially - until she continued doing FS after we were married and promised to stop it. Needless to say, that was the end of the marriage. Beiing with her gave me an insight into their mindset albeit a small sample size (I met a few of her good friends who were also in the sex business). Interestingly all her friends woere sex workers. She didn't have any other freinds. I guess it's hard to have non-sex worrker freinds in those circumstances. A bit off topic I know
