And what do you mean "all he' done"? He fucked up once and did everything to reassure her. In all honesty, he did his part, the best that he could. What's even worse is nothing even happened. That aside, if she couldn't handle it, she also has a responsibility to speak up and say she can't move on or she's going crazy thinking about it.
I don't know why you still don't get it.
The betrayal shattered trust, leaving the girlfriend hurt and paranoid while the boyfriend struggles with guilt and avoidance. Both are stuck in a cycle of mistrust and conflict, hurting each other further. Healing requires honest communication and effort; otherwise, the pain will only grow. Blocking her is not the right action if the goal is to resolve the situation or work toward healing. Yes, it might provide temporary relief from conflict, it ultimately avoids accountability and dismisses her pain, and is only deepening the emotional divide. After all, it could have been avoided in the first place and accidental or not it all start because of his doings.
The boyfriend did his part. It can't always be just him who is making efforts. Before the purple hair girl showed up, he has always avoided women and any circumstances that she might misunderstand. When he entered the company, he also tried to avoid the only female employee they have. After the incident, that he could still not remember btw, he still actively avoided the girl, and made sure MC knew he was avoiding her - no more private messages even if the topic is about work. He also can't just change jobs. He is also tiptoeing around her, not just because of what he did, but because of the MC's family issue he witnessed - which she is very embarrassed about. Hence, he can't just initiate the conversation.
If you don't see that effort from him, idk anymore. It's the MC's part to initiate and talk it out, too, but it's too late now. That window has passed. He never dismissed her pain at all. If anything, he has been trying to cushion it, waiting for her to open up, until she tried to kill him.
Wow this bitch after all he's done he got the audacity to block her. Two stories already testing my anger. I hope the third one won't make me throw my phone
