Am I Overreacting for Being Cold and Distant Toward My Boyfriend After Discovering He Used Multiple Dating Apps During Our Relationship?

Am I overreacting after I found out that my boyfriend has created profiles across different dating apps ? I've (23 - F) been in a relationship with this guy (23 - M) for about 7 years now ( starting from 2018 ) and now I got to know that he joined not one not two but 5 different dating apps and one dating site starting way back in 2020, and even continued using it in 2024 while he was away from me in another city for his job.

When I first confronted him, he told me that 'happn' is NOT a dating app. And then he was like it was a LONG time ago. And then he changed his statement to yes I did it but out of curiosity because I was just 19yo in 2021 and I was just a kid. And then he changed it to yes I wanted to talk to a stranger ( vent ) because I was not there for him. I was always there for him except when he did shitty things to me.

He first made an account on this dating or maybe it was just a hookup site ( Patakadates.com ) in 2020. And then made an account on Tinder, Happn and Bumble in 2021. What is eating me alive from inside is that I connected the dots recently that he created an account on another dating app ( Mingle2 ) in September, 2022 while he was away from me in another city for his one month internship ( He was living with his sister and her husband in that city ) and then again he used the Happn app in February, 2024 while I was in another city for MY job, again in July, 2024 ( while he was with his sister, one day before he left for his job ) and then used the Happn app again in the same month ( July 2024 ) after he moved to another city for his first ever job. He says that he DID NOT use the apps to date, he just wanted to know IF THE APPS DO ACTUALLY WORK IN DIFFERENT CITIES 🥰 and when he moved to the new city he did some dumb shit ( Lied to me on my face and hide things from me about chatting ( behind my back )& exchanging all kinds of social media and number with a girl he JUST met on his plane ) because of which I was not talking to him for a few days and he uses those apps again because I WAS NOT TALKING TO HIM & he felt lonely and just wanted to vent to another girl on a dating app. Lmao.

So the common factor here is that he used the happn app and created an account on Mingle2 app only when I was away from him. How am I suppose to just trust this man ? It's straight up BETRAYAL and CHEATING in my eyes. But obviously he's a master MANIPULATOR and GASLIGHTER so he's like " even you know that I did not go to those apps for dating " " assume whatever you can buy I did not cheat " " I was just a kid " " We were nothing back in 2020 ".

I don't think any man will even think of going on 6 different dating apps and sites while he says that he's in a committed relationship of 7 years. He's making me feel like it's such a small thing and I should just get over it after he tried to justify his actions a million times. Either he doesn't have an answer to my questions or he just says that " I don't even remember it " or makes an excuse ( a very dumb one ). He says I ruined everything :/ Am i seriously overreacting ? Or a man does acts like this and it's normal ?

I can't stop overthinking about everything he does now. Like what if he's doing this or that or anything else. I feel betrayed and no matter how much I try to suppress it...I just can't seem to forgive him or forget about it.

So am I THE ONE WHO'S OVERREACTING ?
