Perfectly reasonable to have those feelings creep up. Even though the results are positive, this fellow is having a direct effect on your relationship in new and unexpected ways. Feeling put off seems like a natural reaction.
Now, how you interpret and act on that feeling is a different matter entirely. Sounds to me that you have already identified the fact that this is not exactly a positive response to the change. That's a huge first step. Have you considered speaking with your wife about it? As long as you keep it about your feelings and not an attack or "opinion" about her or her new relationship, it might be constructive.
