It’s a dilemma that’s more common than you think when online dating turns into an offline relationship.
I am asking because I don’t know if this agreement is assumed on your part or if he explicitly said, “Yes, you and I are exclusive…” or, better yet, “I want to be exclusive with you.” I’ll explain why I bring that up in a moment, but at any rate I agree with you that checking his dating profile seems out of step with having an exclusive relationship with you…
I also wouldn’t even classify this as snooping, per se. You didn’t somehow break into and read his emails or texts.
As such, some of the comments (which I have preserved) bring up points that I have since addressed in this revision.
Right off the top, you mentioned that you and he have agreed to be exclusive.
By chance: You were on his laptop and happened to see that a dating site was on his “most visited” list.
