<human>: Can you succinctly summarize the text in 1-3 sentences?

My stepdad passed away this morning. My brother called me to tell me and I have been crying all day. I am heartbroken. I live five hours from my family, with my husband, and we were going to visit this weekend to say goodbye. It has all been so sudden. His health made a huge decline in the last week. 
I had so many things I wanted to say. I keep crying, thinking maybe he didn't know. We didn't always have the best relationship. I was so angry that he wasn't my own father. My bio dad left in favor of drugs and a new life, and my stepdad stepped up for most of my life to be a dad and support us. He supported my mom and brother and loved me like his own kid. The past few years, I really began to appreciate him. I told him I loved him when we would talk and I began to call him dad after his cancer diagnosis earlier this year. The last time I saw him was a month ago when the cancer caused a fracture in his arm. I thought he would be okay. I thought we had time. 
My brother said yesterday that it seemed like he was waiting for someone. Probably me. And I really hoped he could be held out until the weekend. The family is saying they're glad he isn't suffering anymore. And I feel the same. But I also feel robbed of final moments and closure. I would like suggestions for what I could do to feel better about this. We are on the road now to visit my family and the cremation is tonight or tomorrow. 
My husband also feels sad because we just weren't able to take time off to go up any earlier than his days off his weekend. How do I assure him that it's ok? I don't want him blaming himself.
<bot>: My stepdad passed away. How can I gain closure and get over the regret of final moments unfulfilled? Also, how can I keep my husband from feeling bad about all of this?
