There are hundreds of thousands of people in the world that are quite secure in their primary relationship to allow the one they have chosen as a life mate to see others sexually. Not everyone considers monogamy the only dynamic to a loving and committed pair bond. Google polyamory and get educated. I myself am monogamous but that doesn't mean I don't understand the other dynamic.
The problem I see here is that op seems to have just given in to his wife's desires without having the security that he needs in their relationship to accept what's she's done.
OP: You need to sit down and talk to your wife and make sure you set some boundaaries to your union now that she agrees not to cross. Don't just hope that she will know what you're feeling and worrying about. Don't give her that excuse to meet with him whenever she can until she eventually falls back in love with him and you become the one she visits occasionally in a sexual way.
Get it cleared up with precise boundaries as to what is and is not acceptable.
