I'm not married, but I can add a view from the other side. TRUST has to be the foundation of a stable relationship IMO, it has to come from both sides. I can understand insecurities alot of people, both men and women have them, as well as self driven jealousy, which most of the time is from being insecure. If she's having doubts, about your sincerity and devotion to and in the relationship you 2 have, then you both need to work on making each other feel more secure. She need to feel like you are 110% committed to her, as does she to you. It goes both ways, as it should. Maybe the way you are going out of your way to reassure her that you are committed is whats making her suspect something is going on.
But she is going to have to understand as well that in business sometimes we have to deal with the opposite sex, and she's going to have to get comfortable with it, or its going to continue to lead to issues of mistrust. Jealousy is a nasty demon in a relationship, which can make or break things. She's going to have to realize you aren't the one who deceived her, and move forward if she wants things to progress, other wise you will be fighting this same battle continually.


Stay Strong~~!!!
