Am I the bad one for going back to work after everything that happened in my marriage?.

—I'll take care of her. I'll raise her - he said. Even when his parents offered to stay in custody, he refused. -No, I'll take care of her - he told them. I heard it, but I was also clear from the beginning: —This is a huge responsibility. I'm not ready to be her primary caregiver. Still, he insisted we could handle it. And it ended up staying at practice that the girl was with us and I spent most of the day with her while he worked. The first week I tried to adapt, do my best, learn how to accompany her. But reality beat me fast. She had very strong seizures, she didn't speak, she deregulated with any change or stimulus. One day, something as simple as mistaking the spoon color triggered an intense meltdown. Within minutes everything got chaotic. I started crying, not knowing what to do, and called it desperate. - I can't do it alone... I don't know how to calm her down — I told her. When he arrived and saw her in crisis, instead of helping me or contain the situation, he looked at me and said: —What did you do to him? There i just exploded emotionally I went to my mom's the next day because I felt like I couldn't do it anymore. It wasn't a lack of love for the girl, it was a lack of tools, support and preparation. Then he called me desperate: "I can't do this alone, I need you here," he told me. I came back. But over time I understood something important: I couldn't leave my job or my life on indefinite pause while I was the principal caretaker of something he had decided to take on saying he was going to take over. I'm back to my work then. And there it all went down. "You're selfish," he said to me. And I answered him, with all pain: — Supposedly you were going to take over. You told your parents, you decided... and you ended up using me as the primary caregiver without me being able to really choose. Because I refused to help.... but I didn't accept to carry alone a responsibility that I didn't deserve to take on. Now I'm stuck with the doubt in my chest... Am I the bad one for going back to my job and putting that limit after two years of marriage?.
