<human>: Can you provide a brief rundown of the text in within 3 sentences?

I met my now-boyfriend a while back through a dating site. We have been seeing each other for about three months. After we got together, we both removed our profiles on the dating site and I haven't touched mine since.

Well, a friend of mine randomly came across his profile on the site the other day, and apparently he's been active on it as recently as yesterday.

As someone who's been cheated on in previous relationships, this makes me uncomfortable. He doesn't know I've been cheated on before, by the way. Even though he's done nothing to make me think he would cheat on me (and he's listed himself as "seeing someone" on the site), I still feel uneasy. I don't understand why he would need to be actively using a dating site anymore.

I can't decide whether or not I should bring it up to him. I don't want him to feel that I don't trust him or that I've been spying on him, but at the same time I really value communication in relationships and would want him to tell me if I was doing something that made him uneasy.

What should I do? Should I ask him why he's still on the site, or let it go?
