Sinful behavior at the time of marriage (or just before or after marriage) MIGHT speak to some intent or it might not, so by itself it means nothing. People sin all the time despite on one level not "wanting" to sin.
What is key is not behavior but the disposition of the will. Such a thing might be adduced before a marriage tribunal as one piece of evidence (much more would be required) of no intent to be married, but there are quite a few degenerates these days who have the attitude that they're going to have one last fling before marriage because they are forced to settle down. In fact, they have the fling with the thought that they'll be prevented (by marriage) from being able to indulge in such things ... which is an implicit acknowledgment of the intent to remain faithful during marriage. Anything short of clearcut legal things like prior marriage is very nebulous, and the NO can't be trusted as far as 450-lb. Father Bob can be thrown to properly adjudicate an annulment, given their track-record of declaring annulments on the flimsiest grounds.
Nevertheless, my attitude now is that given the vacuum of authority, I can't impose my judgments or conscience on anyone else. I've known (even Traditional) couples who had gotten annulments and got married again, and I basically treat them as if they were a legitimate couple. If I were a priest, I would not refuse them the Sacraments. I would advise them that they are at great risk of losing their souls, but that's as far as my role as non-pastor would go.
