I hate giving the silent treatment but I don’t know what else to do at this point.

It’s been 2 years that I’ve been talking with this guy. He is 10 years older than me (I’m 21, he’s 31) Everything was going really well in the beginning, until we met 2-3 times. He claimed many times that he rarely talks to other girls. As you may have guessed, this was a lie.

We started talking on March 2021 and by August 2021 he suddenly stopped texting me every day like we used to do. Then he reappeared on November 2021 and stopped again by December 2021. After that I decided to fly back to uni (abroad) to focus on my studies, since there was no reason to stay home. On January 2022 I found out that he was talking to another girl, and everything made sense. And then again on April 2022 we started communicating again. I really don’t understand why I kept giving him a chance. We met a couple of times during the summer and I left abroad again for uni. He called me nearly every day while I was abroad, from September to October. And then guess what. He stopped communicating with me for the whole November. Not even a hi. And ultimately, he came back and this time he stayed. We had 4 hour long calls every single night for the whole December and until this day he calls me every day.

However I found out that, even though it seems serious this time since we’ve been talking so much (before we didn’t even call each other), he still talks with another girl. I stopped checking him long ago, since everything seemed serious and I seemed to be the only one. But I decided to check yesterday, and I found out that he’s been sending things about marriage to a girl he follows.

He called me yesterday evening but I didn’t answer, and he texted me on midnight asking where I’ve been. I didn’t reply. I also have 3 unread messages on insta, I haven’t even opened them. I don’t want to talk to him anymore, this was enough. I didn’t say anything about the other girl, I didn’t confront him, even though I knew about it since last year. Now there’s another girl. And once again I’m the victim. I’m the one that stayed. I am the given that will never leave him.

I hate giving the silent treatment but I’m so hurt again. This will never end. How should I handle this? Should I say something? Or just let it go?
