Guys, Why would he "break up" with me when his mother is dying?

So, we were only together for 2 months but it was so amazing because our love languages meshed and he honestly treated me EXACTLY like I would want to be treated. The entire time we were with each other his mom had terminal cancer and he got news of her declining health and ended it with me. I understand that that is obviously devastating news but I don't understand why he wouldn't want me to be there and support him. We haven't spoken in over 35 days but he randomly unfollowed me on Instagram but kept me on snapchat (still views some of my stories) so I am just really hurt and confused about what to do. Any ideas about why or what any of this means?
