I don't even know if MC knows the extent of the trauma, maybe that it's there. But the ML also kinda forced the relationship to keep MC and MC wanting to believe it would progress well t with it, and instead of lovers it was more of a situationship without intimacy. They both didn't give as much as they could have to communicate things...

K, I'm going to get a lot of hate for this. But I think they are both at fault here. ML was a douche, but he had past trauma, and come on, no one could have sex with that trauma. He was a nice boyfriend if we ignore his bullshit talk of treating MC by saying he will find him an omega. MC is a victim, but I think he overthought most of that. MC hid his trauma from ML, but we expect ML to ignore his trauma. Being with Beta was already hard for him, but he couldn't give up on him because he loved him. MC endured much for 7 years, and ngl, the breakup was deserved, but ignoring the fact that ML broke up with him because he felt guilty about cheating. ML also endured feeling like his father just because of basic desires, having feelings forced on him, and most of all, he felt guilty about sleeping with someone else.
You all understand MC's character, while ML is ignored. I'm not saying MC didn't endure anything, but I'm explaining ML's part, as we all understood MC
