Hmmm interesting. I'll say right off that I am divorced and didn't hobby out of respect for my relationship BUT I didn't have a good sex life with my ex, as a matter of fact it was nonexistent for the last several years of our marriage, and that is one of the many reasons we split up.
I too have been hobbying for awhile I can honestly say that I have run into a similar situation but the prospect of things getting back to those around me prevented me from taking the plunge. In general though, and in your case, I have to hope that provider wouldn't share any information because it puts her at risk as well but the reality is YOU are the one who has a great deal to lose!
GP, NormalBob, Whosdair and many others have shared sound wisdom with me and others on the board and I think that I can paraphrase what many of them have said ... err on the side of caution and if it doesn't feel right or if that little voice in the back of your head is telling you to be cautious ... LISTEN and don't do it!
Sometimes the little head effects our ability to think clearly. But IMHO ... the risk is too great!
Thats just my $0.02
