Because he doesn't have pictures up, it seems safe to say he's not actively looking for potential dates.
It's quite possible that he created the profile before you two started dating and just never bothered to take it down.
Before you decide to do anything, talk with your boyfriend.
Simply tell him what you've told us—without using an accusatory tone—and see what he has to say.
It seems that you may have even gone for years without dating each other.
There are some questions that I want you to ask yourself before you decide whether or not you say anything to your boyfriend: Spend some time and figure out why you are in this relationship, what you want out of the relationship, and how you feel about this specific situation before you talk to your boyfriend.
We are the first and only online profile finder of it's kind that goes out and actively searches over 100 free and paid dating sites to identify other similar or matching profiles created by the same person using the same email address. Online dating has become quite popular in the past few years.
I believe that once you know more about what you want from your relationship, it is important for you to talk to your boyfriend and clear the mystery of this situation.
Open communication is essential for building a trusting and ultimately loving relationship.
And here's what I think: Thanks for reaching out!
So sorry you're in the middle of a rather sticky situation, my dear.
