It sounds like you did cross her boundaries, but I think the definition has to be left between the pair of you really... I would honour what she says in this case. It is very important not to push your guilt / distraught feelings onto her and make this all about you though.
I think it might be worth you read this just in case, though:
http://www.phillyspissed.net/sites/default/files/what%20to%20do%20when%20someone%20tells%20you.pdfIt's a zine called 'What to Do When Someone Tells you that you violated their boundaries, made them feel uncomfortable, or committed assault'.
Obviously in terms of a legal definition it depends upon where you live - my understanding is that some states and countries would define that as assault, others not. It seems as though it is not a legal matter though, which is why I think you need to defer to her judgement.
"She is now feeling worse because I am distraught" is very important though. While I relate, it is not really fair to make her feel worse because of your guilt over what you have done, even though I am sure this not your intention. This is easier said than done, however.
Hope this helps somewhat. Sorry I haven't really provided a definite answer. I don't think people can really speak on your fiancee's behalf in this case.

I also think this should probably be moved to the remorse sub-forum
