Boyfriend for 5 months, we met on POF dating site and I found that he still has account indicating single and I can see that he is on there twice daily on the way to and from work (indicates times he's online). We are in an established exclusive relationship and I have been told numerous times I am the one and he loves me, only one for him, etc. I have met his parents and friends and I would describe our relationship so far really good but my gut at times has told me something is off. What do I do?
I created a false account to monitor his activity.
