Why is my cheating boyfriend mad that I responded to my ex?

So my boyfriend cheated on me with his ex. After much consideration, we agreed to try and make it work. I know what y’all are gonna say, but it was a mutual decision that we made together. Then out of the blue my ex reached out and wished me congratulations on my new job (I also moved to a different state, with my boyfriend). I said thank you, and that’s it. Then I told my boyfriend about this and he flipped out on me for even responding to him… I’m over here like “but… didn’t you also did the same with your ex and it even lead to you cheating… and you were hiding it all from me…?”

On one hand I feel like he doesn’t even have the right to get mad at me. But on the other hand I know he’s scared that I might “take revenge” on him by cheating on him back - which I won’t. I honestly feel like he’s projecting…

Am I in the wrong for feeling frustrated at his anger towards me? He’s coming across as being very hypocritical…
