I would ignore it and not bring it up again...If you do, be prepared for him to back off.

I understand you checking up on him...I would do the exact SAME thing too OP!

But don't let him know you are doing so.

Just act non-nonchalant about it and I am sure that he will delete it soon.

Guys are different than us in that they do not get to stuff like this as soon as we do.

OP, you are spying on him and acting kind of crazy. I would strongly advise NOT telling him that, but instead, it sounds like you maybe should focus on developing the relationship based on the feedback he's actually given you - that he feels the same was you - and make your decisions based on that, not based on perceived activity on the site where you met. If he's going on dates with you 2-4x per week, he's invested. The best way for you to kill a new relationship is to get all suspicious and second guess things. Stop doing that.
