<human>: Give me a shortened version of the text

A couple weeks ago, my boyfriend found out his mom had cancer. Our relationship has been relatively short, around 8 months, but it was going so well until he got the news.

I tried to be as supportive as possible. I was in just as much shock as he was, and it was very difficult for me to cope with the fact that someone I knew had to deal with cancer in their life. 

However, a few days after he found out, he became extremely distant and cold with me. Conversations were cut short, he never showed any emotion, it was almost as if he fell into depression.

I didn't know what to do. I tried my hardest to keep our relationship going, but it was extremely difficult. It was like nothing I said helped him, and he was falling into a more depressed state than before.

I eventually gave up after some hurtful things he said to me. I couldn't take it, and I broke up with him.  He blamed it on me and said that he is obviously going through a hard time and I'm just giving up on him. 

I don't know what to do. This happened Tuesday and I feel like shit. I've never dealt with depression or cancer in my life, ever, and he wasn't being the least bit communicative with me. I was constantly trying to help him (without any prior experience with these matters, it was hard) but it didn't matter, he always cut me short.

Is this my fault? Am I terrible person? I feel like I could still potentially fix this, should I even try? Thanks for reading.
<bot>: Boyfriend's mom got cancer, he fell into what seemed to be depression, and didn't communicate with me whatsoever for weeks. I eventually gave up and I'm not sure if I should try to fix it or not.
