My boyfriend has a secret account where he search other girls on Instagram. Should I be worried?

I saw my boyfriends IG search history showing other girls names. I asked him if it was true and he denied and lied. I told him to show it to me but he refused. He later then showed me but he obviously cleared it beforehand. I told him that I didn’t understand why would anyone need to search up an opposite gender’s profile. And I was not comfortable with it. I’ve never let myself do it either. So I expected the same. I later found out that he used a spared IG account to do this same action of searching up girls. And these girls had 0 connection to him except for maybe Tinder which he used when we broke up previously. The worst is that one of the girls was the one who he hooked up with when we weren’t tgt. But this girl was also the one he talked to when we were still tgt. He just didn’t made any more moves at that point cuz we weren’t broken up yet. I also found out that when we got back tgt, in that same month, he started using tinder again and even asked girls for pics and for them to fly to our country to meet him. He also DMed local girls and asked them out. This was when I was already back tgt with him and gave him another chance. I don’t know how to tell him what I know because I saw this by secretly checking his phone. I wish I was wrong for doing this. if I did this and he had nothing wrong for me to find out, only then I can say I’m the bad person here. But am I really at the wrong here?
