my boyfriend is on dating app

Hi everybody,

I met my boyfriend on a dating app almost 4 years ago. Since then we are in a relationship and live together almost 3 years.

In the beginning I checked once if he was on the dating app and i found him. His excuse was that he was checking if i was using it and that he would delete the app. Now one month ago I created a fake account and found he was online on the dating app and liked his profile. Then he started writing to this fake profile. I asked him if he was on a relationship and he said yes. Then i asked him why he was on the app and he answered that he wasn’t really using the app and that he really liked “me” (fake profile). I said that something must not be good in his relationship and he said that it is good but one thing doesn’t. But doesn’t told me what and i didn’t asked (we are trying to conceive for 2 years now 😥). He asked me if i was anyway interested of making friendship or more with him. I said no and aren’t answering now. He is sending messages all the time. I don’t know what to do! 😥😥 Can you give me some advices please? thanks
